# About

I turn machine-learning theory into working, reproducible systems. My research asks a sharp question about causal video generation and video world models: when does spending expensive per-frame compute only on "hard" temporal segments actually pay off? I build open, auditable artifacts — code, locked protocols, and every result file — so each claim can be checked.

Two first-author preprints (one under review at IEEE TCSVT) and the JevGAG + DDAG programme: a matched T4-vs-A100 study of adaptive temporal granularity, an intrinsic pre-generation probe on the generator's own activations, and a training-free seam repair.

Regime-Aware Temporal Granularity for Causal Video World Models

When does adaptivity pay? A matched T4/A100 audit of the three preconditions — cost, signal, endpoint — with an intrinsic probe and a regime map.
