Nov 1, 2024Month: 2024-11 | Repository: dsi-clinic/CMAP. Two core features delivered and targeted code-quality improvements focused on reliability, reproducibility, and maintainability. Key features delivered: - FCN dropout integration and training configuration: introduced dropout into the FCN model, added dropout config parameter, updated FCN class to include dropout layers, ensured training can handle tuple outputs, and adjusted training configuration (dropout, patch size, learning rate, epochs). Commits contributing: c377168c5109fa0e2020caaadb5a094fbb0e0b01; 443bf57f01a8bb45c3575a1192062d96cf63abfb; 45d7d4e91ca63811742375200fc46751fa6e6e4b; c87a5dfa79deb25abf3e9dbd427677563b5e0c9a. - Path handling and config normalization for data paths: converted pathlib.Path objects to strings for data root configurations to ensure consistent path handling across data loading and configuration. Commits contributing: 6a0c83a167ebba8f0cd6d3de09b9dd3acd65512e; c69f7a1f83aa772252cc5444667dc2957eb67db7. Major bugs fixed / maintenance: - Code quality and maintainability updates: linting/import adjustments, minor spacing fixes, docstring corrections, and pre-commit configuration updates. Commits contributing: 51ad9af8bc71dfb39aa1493be1997854b6d100e7; 3ac9b5a85ff8c98cfcd350fdbaf8734caceaeabc; 496db2bad823275d724fa1a8ac2e57313e482cb2; 6071f62925e49e10fb3af7997721a02603d4f1f6. Overall impact and accomplishments: - Improved model robustness and training stability through regularization with dropout and tunable training parameters. - Enhanced reproducibility and environment consistency via standardized path handling and config normalization. - Reduced technical debt and improved onboarding and CI readiness through targeted code-quality improvements. Technologies/skills demonstrated: - Python configuration management, pathlib usage, and data-path normalization - Model development and training workflow adjustments (dropout integration, tuple outputs handling) - Code quality practices (linting, pre-commit, docstrings, spacing) and CI hygiene. Business value: - Faster, safer experimentation with configurable regularization; more reliable data loading across environments; reduced risk from path-related failures; higher maintainability and faster onboarding for new contributors.
