Predictive Maintenance Master Source Package (src)
Organized into modular subpackages:
- src.preprocessing: Preprocessors for AI4I, Pump, CMAPSS, Azure PdM datasets
- src.training: Classification & RUL Regression model trainers
- src.rag: FAISS vector indexing and SmolLM2 explainer
- src.utils: Shared helpers, EDA visualization, and Production Scheduler
