Projects + writeups
Things I've built and studied, in the order I did them. Mostly sports data and the models around it, with some chips along the way.
- NBA Roster Geometry and Resilience Salary-weighted lineup connectivity adds signal for playoff stability; negative salary assortativity aligns with robustness. Research · 9 min read
- Transformers from Scratch in Rust 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. Build Log · 10 min read
- B.A.I.L.I.F.F. Paired mock trials where only the defendant's name changes. Verdicts can look fair while the trial itself is not, and across six model families the verdict flips on 14.9% to 38.3% of name swaps. Research · 9 min read
- Reading the Shooter, Not the Shot Predicting where a free throw lands from body pose alone, with no ball in the data. We worked out the measurement floor first, then got to 0.00689 MSE. Research · 4 min read
- GroupWAR National-team selection as a search problem: whole rosters scored by a graph network against opponents trying to beat them, and why the search needs rules. Research · 8 min read
- Rebuilding the Wires A toolkit that turns a placed-and-routed chip layout back into a gate-level circuit a SAT solver can drive, and the audit that caught the bugs that would have fooled it. Build Log · 12 min read
- Wrong Answer, Different Wrong Answer 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. Research · 16 min read
- Enumerate, Then Select 1,557 one-line primitive alphas, an overnight factory, and probing the scoring system before spending budget on it. Build Log · 13 min read
- Making a Chip Fall Out of the Workload Reverse-engineering the principles behind OpenAI's Jalapeño inference chip by optimizing an accelerator from scratch and seeing which design choices emerge on their own. Research · 25 min read
- Holes in the Defense A space-control field from broadcast tracking that scores screens, drives, passes and closeouts in one currency, and predicts the next three seconds. With an interactive replay. Research · 10 min read
