Sign language
Cross-lingual transfer for skeleton-based sign-language recognition. A one-transform canonicalisation, the mechanism behind its gain, and an audit of the pose tracker it depends on.

Tactile charts
Converting chart images into 36×60 pin grids for refreshable tactile displays. Chrome suppression, gap pins, and a distribution-free certificate on the miss rate.

From scratch
Standard machine-learning components rebuilt in plain NumPy to see what the frameworks hide. So far: a neural-network library, a 2D physics engine, and a DQN lunar lander built from both.
Prediction markets
Prediction markets (Kalshi, Polymarket) against the CME crude complex: pricing the same events under different mechanics, measures and settlement rules. A cross-checked pricing library, three months of live tracking, and pre-registered hypotheses about the structure under the aggregate agreement.
