Machine Learning Models

This repo contains tutorials to implement various ML algorithms from scratch or using pre-built libraries. This is a living repo and I will be adding more tutorials as I learn more. Hope it will be helpful for someone who wants to understand these algorithms conceptually as well as learn how to implement them using Python.

• 01_Gradient_Boosting_Scratch.ipynb This jupyter notebook has implementation of basic gradient boosting algorithm with an intuitive example. Learn about decision tree and intuition behind gradient boositng trees.

•  02_Collaborative_Filtering.ipynb Builting MovieLens recommendation system with collaborating filtering using PyTorch and fast.ai.

• 03_Random_Forest_Interpretetion.ipynb How to interpret a seemimngly blackbox algorithm. Feature importance, Tree interpretor and Confidence intervals for predictions.
