Marginal Musings

~ Shlomo Stept

Exploring the edges of my understanding.

Writing about computer vision and deep learning from scratch, with forays into reproducibility, document intelligence, and the messy details of real ML research. With an occasional side of context engineering and agent harnessing, and on rare occasions forays into finance, mathematics, and markets.
