Beginner-friendly Machine Learning utility library built from scratch using pure Python

Custom_ML_Suite

Custom_ML_Suite is a beginner-friendly Machine Learning utility library built completely from scratch using pure Python.

This project focuses on understanding the mathematical foundations of Machine Learning by manually implementing core ML algorithms, preprocessing methods, distance metrics, activation functions, statistical operations, and evaluation metrics without using external ML libraries like scikit-learn.
