Jeremy Howard’s legendary top-down deep learning course — you build working models in lesson 1 and learn theory as needed. This course has produced alumni at Google Brain, OpenAI, Adobe, and Tesla. The teaching philosophy is radical: start with practical results, then go deeper. Covers computer vision, NLP, tabular data, and deployment using PyTorch, fastai, and Hugging Face Transformers. If you learn by doing rather than by theory, this is the best deep learning course available anywhere.
