The Data Science and Machine Learning course, prepared by Mr. Venkat Krishna in conjunction with Sea and Beyond is designed to empower maritime professionals—including mariners, engineers, and analysts—to make informed, auditable decisions using data. The curriculum bridges the gap between traditional maritime expertise and modern data science by moving from foundational statistics to advanced AI-ML applications.
A unique and defining feature of this course is its focus on real-world use cases from the maritime environment. By utilizing raw data from main engine parameters (as highlighted in the query), the program allows those from a maritime background to relate directly to the data modelling process. This practical approach is woven throughout the modules, where students apply algorithms like Random Forest regression and classification specifically to marine data, comparing these results with traditional models to evaluate predictions and inferences.
The course is structured into four primary phases:
- Foundations and Statistical Analysis: The journey begins with the data lifecycle, covering collection from IoT devices, cleaning, and Exploratory Data Analysis (EDA). Participants master essential statistical tools such as hypothesis testing, p-values, Z-scores, and probability distributions (PDF and CDF) to infer population characteristics from sample data.
- Core Machine Learning Theory: Learners are introduced to Supervised and Unsupervised learning. The curriculum covers linear and multiple regression, feature engineering, and metrics like RMSE and R² to ensure model reliability. Concepts like degrees of freedom and the Central Limit Theorem (CLT) are emphasized to help students avoid overfitting and ensure their models generalize well to new data.
- Maritime-Specific Applications: The course dives deep into specialized techniques applied to maritime datasets, including Clustering methods, What-if analysis, and Anomaly detection using Isolation Forest. These tools are essential for operational tasks like identifying sensor faults or predicting maintenance needs. Additionally, Time series analysis and moving averages are applied to marine data to enhance predictive accuracy.
- Low-Code Tools and Deployment: To make data science accessible, the course introduces the KNIME low-code platform, allowing users to apply complex regression and classification models to marine data without intensive coding. Finally, participants learn to build and deploy Streamlit applications and use GitHub to manage their work, transforming their models into practical, day-to-day tools for the maritime industry.
This structured roadmap ensures that maritime professionals can transition from understanding "the 3 Vs" of Big Data (Volume, Velocity, Variety) to deploying sophisticated AI agents and RAG systems in a way that is directly relevant to their field.
