AI by Hand: Demystifying Deep Learning with Interactive Workbooks
Prof. Tom Yeh's Substack, AI by Hand, teaches the math, algorithms, and architectures of AI through hands-on, interactive lessons. With over 73,000 subscribers, it offers a library of workbooks and seminars covering topics from attention mechanisms and activation functions to fine-tuning and frontier models like Qwen and Gemma. The approach emphasizes understanding by doing, with visual tools like Matmul Flow and Self-Attention Flow.
Fine-tuning is how you turn a general-purpose pretrained model into something that actually does your task, and getting it right means knowing which…
