Classical ML Toolkit

This repo contains a collection of classical machine learning algorithms and tools implemented in Python. The goal is to provide a simple and easy to understand implementation of the algorithms, so that they can be used as a reference implementation for students and practitioners alike.

Usage

The algorithms are implemented as classes, with the following methods:

• train(X, y): Train the model on the given data.
• predict(X): Predict the labels for the given data.

Implementation may vary slightly between algorithms, but the general idea is the same.
