What it does
Custom temporal transformer ensemble with XGBoost. XGBoost achieves 1.55°F MAE; the custom temporal transformer achieves 1.0°F MAE. Optuna Bayesian hyperparameter search. Converts continuous forecasts to integer probability mass functions across bracket boundaries. Fractional Kelly with a 2% bankroll cap. Full frontend dashboard with auth.
What we learned from it
the accuracy ceiling on day-of weather forecasts is around 1°F MAE for the best ML models. That's tight enough to often pick the right 2°F bracket. If you're going to compete with this kind of bot, you need either a better model (hard) or different markets (easier).
