What it does
AI by Hand is Tom Yeh's English-language publication about AI mathematics, algorithms and architectures. Its archive includes teaching material built around handwritten explanation.
Working through a small example on paper can make an architecture easier to inspect. Use the underlying technical references when moving beyond a teaching example into implementation. New articles and live seminars are free; members receive the full research library. The library lists interactive diagrams and an agentic-AI course with calculations and sample code in Excel.
