I've created a website <a href="https://www.deep-ml.com/" rel="nofollow">https://www.deep-ml.com/</a> where learners can practice and implement machine learning algorithms using only numpy. Now, I'm making all the problems open source on GitHub: <a href="https://github.com/Open-Deep-ML/DML-OpenProblem">https://github.com/Open-Deep-ML/DML-OpenProblem</a>.<p>The goal is to provide a resource where people can dive deep into the fundamentals of machine learning without relying on high-level libraries, making the learning process more transparent and hands-on. Contributions and feedback are welcome!
