Research write-ups and working notes: mostly sports data, models, and the measurement problems that come with them.
A space-control field from SkillCorner's broadcast tracking that scores screens, drives, passes and closeouts in one geometric currency. Picks and drives open empty space, closeouts close it, Voronoi gets the closeout backwards, and the number predicts the next three seconds. With an interactive replay.
An attempt to reverse-engineer the principles behind OpenAI's Jalapeño inference chip by optimizing an accelerator from scratch and seeing which of its design choices emerge on their own. Interactive: real search, ablation and RTL data.
How the Weldon Warriors placed 6th in Canada and top 3% worldwide at WorldQuant's IQC: 1,557 one-line primitive alphas, an overnight factory, and probing the scoring system before spending budget on it.
Vision-language models are being used for action tracking now. I built a test to check whether one was really watching, and the number it gave me turned out to mean nothing.
Salary-weighted lineup connectivity adds signal for playoff stability; negative salary assortativity aligns with robustness.
Every attention variant, RoPE, and a KV cache by hand on Candle, now running a real Qwen checkpoint, with predictions registered before the benchmarks came in.
