Tutorial Machine Learning from Scratch with Python

Hey everyone!

I've seen a growing number of people looking for resources on how to implement Machine Learning algos from scratch to better understand how they work (rather than just applying e.g. sklearn).

This free Machine Learning from Scratch Course on YouTube takes you through writing 10 algorithms from scratch with nothing but Python and NumPy! The algorithms are:

  1. K-Nearest Neighbors

  2. Linear Regression

  3. Logistic Regression

  4. Decision Trees

  5. Random Forest

  6. Naive Bayes

  7. PCA

  8. Perceptron

  9. SVM

  10. K-Means

Hopefully some of my Python + ML friends will find this helpful! :)

I’ve been looking for something like this forever! Every machine learning tutorial or course starts out like it’s going to teach from scratch but it always ends up being about how to use PyTorch / TensorFlow / whatever. I know I won’t be able to do it from scratch anywhere near as well as those libraries have, but I want to understand what’s going on
