Contributed to the IFRI-AI-Classes/ifri_mini_ml_lib repository by building a modular machine learning library focused on dimensionality reduction and model evaluation. Developed and refactored core components for Principal Component Analysis (PCA), t-SNE, and k-Nearest Neighbors (KNN), emphasizing maintainable project structure and clear API design. Enhanced the codebase with robust testing, improved documentation, and streamlined data pipelines, enabling rapid experimentation and reliable results. Leveraged Python, NumPy, and Matplotlib to implement algorithms and visualizations, while reducing external dependencies and technical debt. The work prioritized versatility, allowing multi-task learning and simplified integration for future machine learning experimentation and deployment scenarios.
May 2025 Monthly Summary for IFRI-AI-Classes/ifri_mini_ml_lib: Delivered multi-task capabilities and core data pipeline improvements, with expanded test coverage to ensure robustness and maintainability. Key features delivered: - KNN: Added multi-task classification and regression support; prediction now adapts to a task parameter for versatile k-NN usage. - PCA/TSNE core updates: PCA refactored to operate on raw data by removing centering/normalization; TSNE initialized via local PCA with correct n_components; API alignment to simplify usage. Major bugs fixed / stability improvements: - PCA core refactor to remove standardization, addressing edge-case data handling and improving downstream TSNE behavior. - TSNE initialization alignment with local PCA to reduce misconfigurations and improve reproducibility. - Expanded tests to detect regressions and decouple TSNE tests from scikit-learn dependencies. Overall impact and accomplishments: - Increased model versatility and reliability across the ML pipeline, enabling broader use cases with minimal configuration. - Reduced external dependencies and improved maintainability through comprehensive test suites and API simplification. Technologies/skills demonstrated: - Proficient Python ML implementation (KNN, PCA, TSNE), task-driven multi-task learning, raw-data processing. - Test-driven development, broad test coverage (PCA/TSNE, scalers, evaluation metrics), dependency decoupling, and API design.
