• Add some useful classes, functions and scripts for object detection, nlp, and tabular-related tasks:
  • Object detection: new metrics and callbacks
  • NLP: data preprocessing, tokenizer, traditional embedding techniques
  • Tabular: data preprocessing, gradient boosting models, explainable AI methods
• Add pytest for development testing and github workflows for testing automation
