Machine Learning Feature Extraction Pipeline

machine-learning data-processing feature-engineering typescript
Prompt
Develop a flexible feature extraction pipeline in JavaScript that can process heterogeneous data sources and generate normalized machine learning feature vectors. The system should support multiple input types (JSON, CSV, nested objects), handle missing data strategies, implement automatic feature scaling, and generate scikit-learn compatible output. Include support for custom transformation functions and type-safe configuration.
