Python implementations of some of the fundamental Machine Learning models and algorithms from scratch.
The purpose of this project is not to produce as optimized and computationally efficient algorithms as possible but rather to present the inner workings of them in a transparent way. The reason the project uses scikit-learn is to evaluate the implementations on sklearn.datasets.
Feel free to reach out if you can think of ways to expand this project.
