The Machine Learning & Deep Learning Compendium is an open educational resource that aggregates summaries, links, and articles across machine learning, deep learning, and specialized AI domains. It covers topics ranging from modern ML algorithms and deep learning techniques to LLMs, NLP, audio processing, computer vision, time-series analysis, and graph methods. Originally a personal learning document, it now serves as a knowledge-sharing project designed to help data scientists, academics, and beginners access curated references efficiently.
