To get actionable information, most BI tools require you to follow a number of complex steps and even coding. However, that’s now how Power BI functions. The Q&A feature Power BI comes with allows you to ask questions using a natural language and get the information you want. For instance, if you want to check the number of shoes sold. You can simply visit the Q&A section and enter “shoes sold by the state as a bar chart” This will display the information you need in the form of a bar chart. How Can You as a Business Benefit from Power BI Dashboard? Imagine you’re selling shoes/t-shirts on your website globally, and receiving thousands of queries and sales each day from customers. Also, you’re running marketing campaigns to improve your sales. Now, how will you answer the following questions: Well, if you have a few hundred customers, maybe you could manually check the data to answer these questions. However, if you have thousands of customers to deal with each day, manually checking the data would be a bad decision as it would be both time-consuming and ineffective. And this is when Power BI comes in. With Power BI Dashboards, no matter how much data you deal with each day, you can easily answer all of the above questions within minutes. You just need to select the data source, select the attributes, do some dragging and dropping, and you’re done. Power BI Dashboard basically helps you structure all types (structured, semi-structured, or unstructured) of data into a visually immersive and easy-to-understand format. And once you can understand the data easily, you can make better, well-informed, and data-driven decisions that benefit your business. What are the Use Cases of Power BI Dashboard? Regardless of which domain you belong to, if you have to deal with lots of structured, semi-structured, or unstructured data, Power BI is for you. So, in this section, we’ll talk about different departments within a company that uses or can use Power BI Dashboard. Here are the top most common use cases of Power BI Dashboard: Management The c-level executives can use the Power BI dashboard to understand operational KPIs such as profit, loss, net revenue, customer retention, etc. Dashboards also give insights into investor summaries and financial overviews. Here’s what a management Power BI Dashboard looks like: Finance The CFO and other folks in the finance department can have an overview of

Leveraging AI in manufacturing helps company transform their business completely.  Let’s explore how top AI companies in manufacturing industry are paving the path for automation and digital transformation. What Is AI In Manufacturing? AI in manufacturing is, adding advanced technology to the current manufacturing process. It can get used to automating complex tasks and trying different manufacturing patterns for a fast workflow. Without artificial intelligence, it would take hours to complete a task that an AI system could do in seconds. Furthermore, it will also affect work efficiency. In many cases, it is difficult for humans to detect defects in a product because they are not visible to the naked eye.  On the other hand, manufacturers that adopt AI use it to improve equipment efficiency in production, uptime, and better prediction. Manufacturers can track their facilities in real-time. Thanks to critical Fourth Industrial Revolution (4IR) technologies. It includes ML, automation, advanced and predictive analytics, and IoT (Internet of Things). McKinsey conducted a survey which results that the 4IR technologies are capable of generating approx. $3.7 trillion in value by 2025. AI has the potential to generate $1.2-$2 trillion in value only in manufacturing.   AspenTech research shows that 83% of large industrial companies believe that AI can produce better results. It also suggests that domain expertise is core for adopting AI models into the manufacturing industry.  To stand up in this competitive race, manufacturers have to adopt a data-driven business model. This includes skilled staff, advanced hardware, and ai software. How AI is Changing Manufacturing? The need for 4IR technology will lead manufacturing businesses into the world of digital factories. The IFR  (International Federation of Robotics) report shows that there are 2.7 million robots currently operating in factories worldwide. And with the increase in digitization, this trend is growing in speed.  In the recent global epidemic, some manufacturers adopted technologies to make their businesses more flexible. That includes automating operations and ease of end-to-end control over all operations. Many manufacturers are still trying to adopt AI and ML-like modern technologies to reduce production costs and increase time-to-market. Following are some of the solutions of AI and ML that most manufacturers have adopted. Workplace Safety This is one of the most common places where manufacturers can use artificial intelligence. AI gets used for workplace screening and safety. This technology was most useful during the pandemic time. AI is used to identify employees’ health status using thermal screens.  AI monitored employee interaction and contact for workplace sanitization in case of emergency. Also, the same system can help keep employees healthy, safer workplace, and continue work in the future. Machine Maintenance All manufacturers always try to maintain their important production machinery. AI and ML are useful in advance maintenance management. It helps manufacturers to shift from regular maintenance to predictive maintenance.  It will result in a large amount of reduction in regular maintenance efforts, annual maintenance costs, and part maintenance. With the help of AI software, hardware sensors, machine data, and AI, the maintenance team can identify the major failures. It also helps in predicting future failures. Security Research suggests that manufacturers experience a lot of damage during cyberattacks. As production industries are increasing the number of IoT devices in their factories, it affects the growth in cyberattack chances. Smart factories are getting on target for cyberattacks. AI-based cybersecurity software and risk detection can help in securing production factories. It can also help in reducing attack risk.  Manufacturers can use self-learning AI software to secure their IoT devices and cloud services. As this AI can spot attacks and interrupt them in seconds with accuracy. The system can also alert and provide guidance to prevent further damage.  Benefits Of AI In Manufacturing  Manufacturers are preferring AI robots in their business. The ultimate aim is to provide a safe workplace and increased efficiency. Following are some benefits of AI in manufacturing as well as in AI as a service. Cost Reduction in AI solution The major advantage of AI as a service in a company is that it allows the reduction of the development cost of AI solutions. You only have to pay for what you need.  IBM Watson and Google cloud storage are the best examples of AI as a service. As they charge businesses as per their use.   Quality Control The key advantage of AI and ML in the manufacturing industry is quality control. Advance machine learning models can get used to differentiate normal design and faulty design. ML model can identify the minor faults that humans can’t notice.  Adding such systems into the quality assurance section will increase product quality and also save time and money. 24/7 Production With the rise of worldwide product demand. If any production facility plans to work continue round the clock, they need to create different work shifts. They have to use 3 human workers for every 24-hour period. At the same time, robots don’t get tired or feel hungry. They are capable of working 24/7 in any condition.  This will affect an increase in production capability and manufacturers can meet the product demand. Additionally, robots are more efficient in picking and packing sections. They can help in reducing the required time in many areas. Top AI Companies in Manufacturing Industry A case study shows how manufacturing companies like Micron Technology have faced mechanical issues while developing their product. And how AI technology adoption has saved their hours of downtime and Avoided the loss of millions of USD through early detection of machine breakdowns and quality issues and a 10% increase in manufacturing output.

4 Best Computer Vision Use Cases for Solving Business Challenges

Computer vision is a field of artificial intelligence (AI) that can be found in an increasing number of business use cases. It enables machines to “see” objects and interpret them as humans do. Computer vision services specialize in many types of vision, including detection, identification, and supervision. Here’s a quick rundown of both how the technology works and how businesses are using it to overcome challenges and optimize workflows. How Computer Vision Works All computer vision devices and applications utilize AI, which is a simulated form of human intelligence and the basis of all machine learning. Just as a human sees an image and processes an appropriate response, the AI in computer vision detects digital images, analyzes the data, and processes a response in the blink of an eye. For a computer vision system to work effectively, developers must expose it to thousands of images with definitive traits, such as names, physical features, and labels. Pattern recognition is the name of the game. Once the system acquires a knowledge base of its particular environment, it can automatically take over detection, identification, and supervision responsibilities without human assistance. Computer vision is gaining a foothold in various industries, and business leaders have many opportunities to use the technology and get ahead of their competitors. Here are four of the most influential applications and real-world examples of how computer vision can solve companies’ challenges. Computer Vision Use Cases for Solving Business Challenges 1. Object Detection Object detection is the most well-known and widely used computer vision function. A system utilizes its AI network to identify specific objects in various settings. It eliminates much of the programming and guesswork that previous detection devices relied on, allowing for quick and accurate detections without human supervision or intervention. Self-driving cars are perhaps the most well-known examples of AI-powered object detection, but that technology has seen mixed results in practice. These other real-world applications have been more successful: Object detection is just the first step in a computer vision service’s analysis. It also classifies, monitors and verifies objects based on what the AI has learned. This technology will only get more accurate as it continues to gather information. 2. Optical Character Recognition On a smaller scale, computer vision services use optical character recognition (OCR) to identify letters, numbers, and other symbols from images. The most mainstream example of OCR that you might have already used is Google Lens. This tool enables users to pull fragments of text from digital images and printed documents and even translate foreign languages from photographs. OCR has also been a valuable tool for several key societal institutions, including education, finance, and government. Universities can scan and extract text from obscure historical documents and make more accurate translations, preserving precious knowledge from the past that otherwise might have been lost. Banks and credit unions offer OCR services so customers can scan their checks and credit cards without coming into the office. Other machine-readable personal documents — passports, driver’s licenses, green cards — also utilize OCR to help governments with border security and identification. Virtually every scannable item you can imagine can benefit from OCR, so your business is sure to find a relevant use for it. 3. Risk Management Employee safety should be the top priority for all businesses and industries, but equipment and regulations can only do so much. A computer vision system can help create a safer work environment by tracking worker activity, including how they use heavy machinery and navigate the work site. Safety-oriented computer vision applications are most common in dangerous settings, such as construction sites and warehouses. Workers use wearable AI devices to monitor their physical conditions, while supervisors use drones and cameras to identify hazards and ensure everyone follows required safety procedures. The health care industry has found a similar use for computer vision services, providing patients with wearables that automatically monitor specific conditions and send feedback in real-time to their doctors. This trend arose by necessity during COVID-19, as many people were either unable or unwilling to schedule in-person appointments. Computer vision is also a key part of some in-house hospital equipment. Medical professionals can train AI to identify the early stages of illnesses through X-rays, MRIs, and CT scans. 4. Image and Video Restoration Modern cellphones, cameras, and editing tools allow people to make drastic changes to images and videos, but none of those devices come close to computer vision’s editing capabilities. Computer vision services restore pictures and videos with extensive damage and decades of deterioration. AI in computer vision services evaluates the missing or damaged parts in the original image or video, reads a generative model of the same media, and fills in the gaps to recreate the scene. Some take the restoration a step further and build 3D sets of real settings, such as archaeological and environmental professionals.  Computer vision’s restoration abilities have also proven valuable in the court of law, as forensic specialists can perform more immersive crime scene reconstructions and thus solve many cases. Computer Vision Has Massive Potential These applications of computer vision services are just a handful of successful examples. This technology has massive potential to transform many crucial industries, from health care to finance to construction. Developers are still working out some of the kinks, but business leaders should embrace this technology and add it to their operations in any way they can.

How Connected Cars and Quantum Neural Network Can Help Drivers in Emergencies

Quantum neural networks are built based on quantum computing and classical physics to deliver accurate and reliable predictions. Our proposed model will make cars self-capable to handle emergencies. We’ll discuss the internal working and modules of our quantum neural network model for connected cars.  Quantum neural networks are created using the principles of quantum mechanics. These are typically feed-forward networks where the information collected in the previous layers is analyzed and forwarded to the next layer. Deep neural networks (DNNs) are already used in developing autonomous vehicles to define the right driving behavior for a vehicle. A Quantum neural network aims to assist drivers in effectively handling emergency situations.  Providing emergency support to car drivers using connected cars and quantum neural networks can reduce the risk of accidents and help drivers reach their destinations faster. This can potentially save lives, especially when driving to hospitals or emergency units. Quantum neural networks are more reliable and accurate than conventional neural networks.  Introduction to Connected Cars and Quantum Neural Network Model  A new system/ device will be embedded in the vehicle’s dashboard to provide support to drivers in emergency situations. The system offers second-to-second continuous support and is specifically designed to handle emergency or complex situations. The system collects data from the vehicle’s sensors and sends it to the connected cloud drive. This data will be processed using quantum neural networks built on the principles of quantum computing and classical physics. The concept of using quantum neural networks and connecting cars (through shared cloud data) is different from the existing approaches used in the industry. This model will be faster, reliable, accurate, and efficient enough to handle the worst-case scenarios people might experience when driving.  Resources Required for the Model  Data is the primary resource for this model. The quantum neural network model requires data from three sources to understand the situations, driving behavior, and the vehicle’s overall performance.  Descriptive Data  This data is about the car and its performance. The data is collected from sensors embedded in the engine, suspension, brake, tires (air pressure), etc. This data will be used to identify car’s health and quality. It also provides information about what’s happening in the car every second. The quantum neural network model will be able to provide a suitable solution when it knows the car’s strengths and limitations.  Navigational Data  This data is related to the routes, navigations, and trips you take in the car. The model collects data from maps to determine the current location, destination, route map, etc. It also gathers data from side impact detection sensors, blind spot detection sensors, cyclist and pedestrian detection sensors, etc., to pinpoint your exact current location.  Behavioral Data  Behavioral data deals with drivers’ performance and abilities. The data is extracted from the sensors embedded in the dashboard. Different sensors are used to collect data necessary for the quantum neural network model to understand the driver’s health and current condition. The sensors help determine who the driver is and suggest a solution according to their driving history (collected and stored in the connected cloud).  Heartbeat sensors, eye-tracking sensors, and fingerprint sensors on the steering wheel are used for data collection. Sensors that track the driving patterns are also used to determine the abilities of the driver. Workflow of the Proposed Model Working Process of the Quantum Neural Network Model  The entire proposed concept will have four steps or modules:   Each module has a definite purpose and streamlines the data flow within the model to arrive at the desired outcome. The second module is where the majority of the work happens. It is divided into three sub-modules. Let’s explore each module in detail.  1. Data Extraction As the name suggests, the data collected from multiple sensors in the car and stored in the cloud are extracted into the APIs. The process of collecting data from the car’s sensors and sending them to the connected cloud drive is continuous. The vast amounts of data are then directly sent to the APIs, where preprocessing occurs.  2. Data Preprocessing  The APIs transfer the data to preprocessing module, which has three sub-modules to prepare the data for analysis.  Data Cleaning  The first sub-module cleans the data extracted from the connected drive APIs. This is a necessary step to improve data quality and increase the accuracy of the quantum neural network model.  Naturally, data collected from multiple sensors will have issues such as wrong image frames, incompatible data formats, corrupt data values, incomplete/ missing data values, etc. This will affect the quality of the final outcome. This sub-module uses different techniques and tools to clean data and repair the wrong image frames. It tries to resolve the missing/ incomplete data or remove it totally. Statistical techniques are used to identify the issues with data and clean it accordingly.  Data Preprocessing  Preprocessing is similar to structuring and formatting data in large datasets. This sub-module prepares the cleaned data to make it ready for transformation, training, and predictions. The data is categorized based on its source.  For example, data from the cameras are sent to the video processing module. Data from heartbeat sensors go to the numerical processing module, and so on. New data categories will be created to sort the cleaned input data into neat segments/ types, making it easy for the quantum neural network to process.  Data Transformation  The last sub-module of the preprocessing stage is data transformation. Here, the preprocessed and sorted data is transformed to create a summary of what it contains. This helps understand the actual meaning of the data before it is fed into the quantum neural network for predictions. The transformed data is analyzed to arrive at the summary and is fed into the learning phase of the system.  3. Training and Predicting Outcomes using Quantum Neural Network Model  This module deals with training the quantum neural network to become capable of working with large datasets and delivering accurate predictions in less time. The data transformed in the previous module is fed

Dimensionality Reduction Techniques in Data Science

Dimensionality reduction techniques are basically a part of the data pre-processing step, performed before training the model. Analyzing data with a list of variables in machine learning requires a lot of resources and computations, not to mention the manual labor that goes with it. This is precisely where the dimensionality reduction techniques come into the picture. The dimensionality reduction technique is a process that transforms a high-dimensional dataset into a lower-dimensional dataset without losing the valuable properties of the original data. These dimensionality reduction techniques are basically a part of the data pre-processing step, performed before training the model. What is Dimensionality Reduction in Data Science? Imagine you are training a model that could predict the next day’s weather based on the various climatic conditions of the present day. The present-day conditions could be based on sunlight, humidity, cold, temperature, and many millions of such environmental features, which are too complex to analyze. Hence, we can lessen the number of features by observing which of them are strongly correlated with each other and clubbing them into one.  Here, we can club humidity and rainfall into a single dependent feature since we know they are strongly correlated. That’s it! This is how the dimensionality reduction technique is used to compress complex data into a simpler form without losing the essence of the data. Moreover, data science and AI experts are now also using data science solutions to leverage business ROI. Data visualization, data mining, predictive analytics, and other data analytics services by DataToBiz are changing the business game. Why is Dimensionality Reduction Necessary? machine learning and Deep Learning techniques are performed by inputting a vast amount of data to learn about fluctuations, trends, and patterns. Unfortunately, such huge data consists of many features, which often leads to a curse of dimensionality.  Moreover, sparsity is a common occurrence in large datasets. Sparsity refers to having negligible or no value features, and if it is inputted in a training model, it performs poorly on testing. In addition, such redundant features cause problems in clustering similar features of the data. Hence, to counter the curse of dimensionality, dimensionality reduction techniques come to the rescue. The answers to the question of why dimensionality reduction is useful are: Now let us understand which algorithms are used for dimensionality reduction of data with examples. What are the Dimensionality Reduction Techniques The dimensionality reduction techniques are broadly divided into two categories, namely, 1. Linear Methods PCA Principal Component Analysis (PCA) is one of the used DR techniques in data science. Consider a set of ‘p‘ variables that are correlated with each other. This technique reduces this set of ‘p‘ variables into a smaller number of uncorrelated variables, usually denoted by ‘k‘, where (k<p). These ‘k‘ variables are called principal components, and their variation is similar to the original dataset. PCA is used to figure out the correlation among features, which it combines together. As a result, the resultant dataset has lesser features that are linearly correlated with each other. This way, the model performs the reduction of correlated features while simultaneously calculating maximum variance in the original dataset. After finding the directions of this variance, it directs them into a smaller dimensional space which gives rise to new components called principal components. These components are pretty sufficient in representing the original features. Therefore, it reduces the reconstruction error while finding out the optimum components. This way, data is reduced, making the machine learning algorithms perform better and faster.  PrepAI is one of the perfect examples of AI that has made use of the PCA technique in the backend to generate questions from a given raw text intelligently. Factor Analysis This technique is an extension of Principal Component Analysis (PCA). The main focus of this technique is not just to reduce the dataset. It focuses more on finding out latent variables, which are results of other variables from the dataset. They are not measured directly in a single variable.  Latent variables are also called factors. Hence, the process of building a model which measures these latent variables is known as factor analysis. It not only helps in reducing the variables but also helps in distinguishing response clusters. For example, you have to build a model which will predict customer satisfaction. You will prepare a questionnaire that has questions like, “Are you happy with our product?” “Would you share your experience with your acquaintances?” If you want to create a variable to rate customer satisfaction, you will either average the responses or create a factor-dependent variable. This can be performed using PCA and keeping the first factor as a principal component. Linear Discriminant Analysis It is a dimensionality reduction technique that is used mainly for supervised classification problems. Logistic Regression fails in multi-classification. Hence, LDA comes into the picture to counter that shortcoming. It efficiently discriminates between training variables in their respective classes. Moreover, it is different from PCA as it calculates a linear combination between the input features to optimize the process of distinguishing different classes.  Here is an example to help you understand LDA: Consider a set of balls belonging to two classes: Red Balls and Blue Balls. Imagine they are plotted on a 2D plane randomly, such that they cannot be separated into two distinct classes using a straight line. In such cases, LDA is used, which can convert a 2D graph into a 1D graph, thereby maximizing the distinction between the classes of balls. The balls are projected to a new axis which separates them into their classes in the best possible way. The new axis is formed using two steps: SVD Consider data with ‘m‘ columns. Truncated Singular Value Decomposition method (TSVD) is a projection method where these ‘m‘ columns (features) are projected into a subspace with ‘m‘ or lesser columns without losing the characteristics of the data. An example where TSVD can be used is a dataset containing reviews about e-commerce products. The review column is mostly left blank, which gives rise to null values in the data, and TSVD tackles it efficiently.

We’ll discuss depression and the ML Python code used to analyze data. The changing lifestyle and social scenarios have brought many changes to our lives. We have access to too much information. We are way too connected with the virtual world, and the lines between real and virtual are blurring rapidly. While it sounds like a good thing to stay up to date and informed about anything under the sun, it also has severe side effects.  The fast-paced world has resulted in a lot of anxiety and stress, leading to different psychological issues in people. Depression and poor emotional health are now among the major concerns across the globe. Thankfully, technology is coming to the rescue yet again. Machine learning engineers and researchers are working on analyzing depression in people to detect the symptoms at earlier stages and provide better ways to cope with mental health issues.  Artificial intelligence and machine learning algorithms can be used to analyze datasets with depression-related data to deliver accurate and in-depth insights. Let’s understand what depression actually is and how ML can provide a feasible solution to help people with depression and make their lives happier.  What is Depression?  Depression is a serious mental illness that makes you feel sad, lonely, tired, or anxious. It makes you lose interest in things you previously enjoyed. Depression is a psychological disorder that increases negative thoughts and emotions, leading to other health conditions. It also reduces your productivity, alertness, and ability to think coherently. It affects how you think, feel, and act.  Depression is a common condition seen in many people. Many times, people themselves don’t realize that they are in depression. Statistics show that around 3.8% of the global population suffers from depression. This includes 5.7% of adults who are aged over sixty years and 5% of adults aged less than sixty.  To put it in figures, 280-310 million people have depression. What’s alarming is that more than 800,000 people commit suicide due to depression every year. Kids and teens are by no means safe from depression. The US is among the states with the highest depression rates around the world.  Depression (Major Depressive Disorder, MDD) is commonly known as clinical depression. MDE (Major Depressive Episode) is a measure of time a person exhibits or has the symptoms of depression. Note that mood swings and short bursts of anger/ irritation are not considered depression.  Different Types of Depression  Depression is an umbrella term that covers more than one type of mental illness/ disorder. It can be classified into the following types:  Anxiety/ Distress  Anxiety is when you feel stressed and tense throughout the day. It brings negative thoughts about how things can go wrong or that something really bad will happen to you or your loved ones. So much worry takes over your mind and your thoughts. It also leads to anxiety and panic attacks.   Agitation  You feel uneasy and uncomfortable no matter what. You cannot relax and calm down. An agitated person has jerky movements and is constantly fidgeting or in motion. You cannot sit in a position for more than a few seconds. Some people also tend to talk a lot when agitated. It doesn’t make sense, but you can’t control it either.  Melancholy  Melancholy is intense sadness or emotional pain. It fills your mind to an extent where even good things don’t cheer you up. Activities you usually enjoy also fail to make you happy. Melancholy results in loss of appetite, sad thoughts, feeling down/ low in the mornings, disturbed and irregular sleep patterns, and suicidal thoughts.  Persistent Depressive Disorder Persistent Depressive Disorder is when a person is suffering from depression for more than two years. It is a chronic condition where the person is highly vulnerable and susceptible to making harmful decisions. PDD is used to describe chronic major depression and dysthymia (low-grade persistent depression). The symptoms of this disorder are:  What is Bipolar Disorder?   Bipolar disorder is also called manic depression, as it causes extreme mood swings in a person. You might experience random bursts of energy where you feel fantastic and at the top of the world. You work and overdo things until you’re exhausted. Meanwhile, on the other end of the spectrum, you’ll feel miserable and horrible about anything and everything. You feel fatigued, tired, and worthless.  This is a vicious cycle where you alter between two contrasting moods but no middle ground. Doctors recommend mood stabilizers like lithium and calming activities like meditation to bring some sort of balance and stability to your mood.  Symptoms and Warning Signs of Depression Depression has many symptoms, some of which overlap with a general lack of mood or exhaustion after a long day of work. Naturally, all of us feel low at some point in our lives or another. But when the feelings persist and take over our lives, it is a sign of depression.  Depression isn’t general sadness or pain of loss. It is more intense and can wreak havoc in your life by gradually robbing your happiness and ability to assert yourself. You can no longer feel, think, work, enjoy, and act the way you used to do. Some people term it as ‘living in a black hole’, where the void sucks out even the last bit of energy and happiness from you.  Some feel apathetic to their surroundings. Nothing matters to them anymore. Others have a constant sense of impending doom and cannot consider a positive alternative. Men exhibit signs of anger and restlessness, while women have excessive feelings of guilt, sleepiness, hunger, etc. Obviously, this varies from person to person.  Apart from this, all the above-listed symptoms are warnings signs of depression. A person who exhibits such signs needs medical intervention as soon as possible.  Datasets Used to Analyze Depression  Using the following datasets,

Self-Service Analytics Framework (Infographic)

More than 60% of the collected data is not used for analytics. This is due to the excessive load on the IT department to handle all data requests while troubleshooting and providing maintenance support.  Self-serving analytics can solve the problem and help employees make the most of data by running analytics at each vertical and department in the enterprise. The self-serving framework is a part of the big data implementation project.  Business Needs                                                                         Convert the business needs into use cases to define the analytical framework in the enterprise. It helps create a proper data flow for uninterrupted data analytics and insights.  Data Architecture  The big data architecture should align with the business needs and long-term goals. It should be flexible, scalable, and secure.  System Integration  Which existing applications are important for the business? How do the applications use the insights derived from the big data model? Integrate the systems to streamline the workflow.  Data Quality  Get rid of poor quality and duplicate data by establishing data governance regulations. Derive better and more accurate insights.  Coding  It’s time to turn the design into code and build the big data pipeline in the enterprise (either on-premises or cloud servers).  Training Employees  Finally, train and empower employees to use data analytics and data visualization tools to derive insights without relying on the IT department.

AI and Data Science: What These Machine Learning Terms Mean for Business

Artificial intelligence is now more available to businesses. The top applications of AI being used by their organizations are data protection, and process automation. Additionally AI is used in customer service. AI may dramatically reduce costs, and improve production and efficiency. It opens doors to new markets and products and enhances access to existing ones. Data science on the other hand has several advantages for a firm. One of a data scientist’s key responsibilities is to analyze and organize your company’s data so that you may get more precise insights from it. Both AI and data science are important ML terms that have several applications in businesses. What Is Artificial Intelligence (AI)? The imitation of human thinking by machines is known as artificial intelligence (AI). These devices are designed to behave and think like humans. It also refers to any computer that demonstrates characteristics of the human intellect, such as learning. With the use of machine learning (ML), which is a form of AI, software programs may anticipate outcomes more accurately. It does this without having to be explicitly instructed to do so. Machine learning algorithms use historical data as input to anticipate new output values. What Is Data Science? Data science is the study of how to extract useful information from data for business decision-making, strategic planning, and other purposes by using cutting-edge analytics tools and scientific concepts.  Data science encompasses a variety of ideas, including statistical analysis, data analysis, machine learning techniques, data modeling, data preparation, etc. In addition to employing algorithms and other methods, data scientists also significantly rely on AI. They rely particularly on its subfields of machine learning and deep learning, to build models and make predictions. Impacts of Data Science on Business It Helps in Recruiting Regardless of sector, finding and keeping qualified staff is a challenge for many firms. Businesses may be quite precise about the kind of individual they are wanting to recruit. This is because of their ability to choose resumes based on a certain character and personality attributes. Data science models can “read” resumes using special algorithms to determine whether or not a prospect is worth pursuing. Natural language processing (NLP) which is a subfield of data science helps firms locate better applicants more quickly. It does this by automating parts of the hiring process such as HireLakeAI which is a smart recruitment solution that helps in screening job candidates and choosing the best as per the requirements. Helps in Making Smarter Decisions Businesses require data scientists to evaluate and extract valuable insights from the data. This is due to the exponential growth in data volume. Data science enables organizations to evaluate information on a wide scale. It also enables them to develop the appropriate decision-making methods. It provides insightful findings. Evaluation and assessment of the many relevant factors are necessary while making decisions. One advantage of data science is improved decision-making. This is due to the tools we can develop to examine data in real-time, giving business managers more agility. This is accomplished using both dashboards and the projections made feasible by the data scientist’s handling of the data. For Making Better Products to Suit Customers’ Needs. Businesses should be able to draw people to their items. Customers’ needs must be taken into account while creating products as well as innovating existing products. Businesses must always guarantee customers’ satisfaction. To create their products in the best way possible, industries need data. Analyzing user feedback helps determine which goods are the greatest match for customers. Data science’s cutting-edge analytical techniques are used for this analysis. Additionally, businesses use the prevailing market trends to develop a product for the general public. These market trends give firms information about the demand for goods right now. Innovation helps businesses grow. Industries are now able to apply a variety of cutting-edge tactics in addition to newer items thanks to the development in data. Improves Data Security and Helps Interpret Complex Data The work done in the field of data security is one of the advantages of data science. For example, data scientists work on fraud protection solutions to safeguard the clients of your business. However, he can also look for regular patterns of behavior in a business’s systems to spot any potential architectural issues. When we wish to combine different types of data to better understand the market and the business, data science is a fantastic answer. For better visualization, we can combine data from “physical” and “virtual” sources depending on the techniques we use to obtain it. How AI Impacts Businesses? It Guarantees Safe Operations Software applications with AI capabilities are being used by other industries for monitoring. For instance, firms are utilizing computer vision and AI software to track employee behavior. This makes sure they are adhering to safety rules. Similar to this, businesses of all sizes may utilize AI to analyze data collected from local Internet of Things (IoT) ecosystems. This helps to monitor workers or infrastructure. After the data is analyzed, the AI models are trained on this data. Then a model registry can be used to store this trained AI model. The AI systems keep an eye out for risky situations and warn businesses about them, such as delivery truck drivers who are texting while driving. For Smarter Supply Chains Businesses from many sectors are utilizing AI to manage their supply chains better. They are forecasting what supply will be required. They also forecast the best time to transport supplies using machine learning algorithms. In this use case, AI assists businesses in building more cost-effective, efficient supply chains. It does this by reducing, if not eliminating, overstocking and the possibility of running out of in-demand goods. For Customer Experience Service and Support Customer experience, service, and support are three of the most popular organizational use cases for AI. For instance, chatbots employ NLP and ML algorithms to comprehend user requests and answer properly. And they accomplish it more cheaply and more quickly than human labor can. AI also
