Improving Maritime Safety With Artificial Intelligence

Our client followed a system to analyze the data that required the manual intervention of the stakeholders. This was the process followed by them:

Our Proposed Solution:

We understood the challenges in depth and devised a 3 part solution to address them:

• 
  Automating the process of converting the data into the desired format.
• 
  Automating the process of filtering incidents that need to be analyzed.
• 
  Using advanced machine learning techniques and incorporating automation into the existing risk model.

I. Data Conversion

For automating the data conversion process, these were the steps we followed:

• 
  Identify the various formats in which the data was being collected, such as Excel, PDF, simple text, JSON, or even scanned documents. The parameters and fields in the data were also identified.
• 
  Mandatory and non-mandatory column mappings were segregated.
• 
  With the help of the stakeholders and marine experts, we understood the meaning of different parameters and created our own mappings with different customer parameters.
• 
  We used advanced text similarity and rule-based engines to compare and match the customer parameters with the data parameters that we had created. This was done to check the similarity of the data and convert it to the desired format.

The workflow was as follows:

II. Data Processing

• 
  After collecting data from multiple sources, the next step is filtering the customer incidents data.
• 
  The concerned mariners will assess the incident data and determine whether to keep or exclude any data.
• 
  Once the filtering was done, mariners check the pending incidents and finalize the dataset
• 
  To streamline this process we developed Auto Data Processing API which automatically filters the incidents data. This API is powered by a combination of approaches such as a rule-based model, advanced text classification model (BERT), and reinforcement learning model.

The workflow was as follows:

III. Risk Model Automation

The risk model being used by our client had many limitations such as:

• 
  The expertise of mariners played a crucial role as they were the ones responsible for conducting statistical calculations, thereby creating a dependency on them for any necessary tasks or alterations.
• 
  The existing risk model was complex because of the heavy calculations involved in the core.
• 
  Running the risk model on a fresh dataset required a considerable amount of time, with each calculation taking around 12-13 hours. This extensive waiting period made the process significantly time-consuming.
• 
  To automate the risk model, we created a hybrid approach that combined the rules and statistical analysis traditionally used by mariners with machine learning algorithms for training and analysis. This allowed the system to predict outcomes without significant time delays. By incorporating machine learning, we aimed to enhance efficiency and timeliness in the prediction process.

The solution was divided into 2 parts:

1. Model Training

2. Risk Model Workflow
