jgrusewski 023c62da28 test(magnitude_distribution): assert on EVAL_INTENT (pre-Kelly-cap), not EVAL_DIST
Pre-existing test bug: line 164 asserted `ef >= 0.05` (post-Kelly-cap
eval_dist), which gates on Kelly cold-start warmup completing within
the smoke's training horizon — not on whether the Q-head learned to
prefer Full magnitude. On the local-laptop smoke (1 quarter MBP-10),
Kelly warmup never completes, pinning eval_dist[Full] = 0 even when
Q(Full) > Q(Half) clearly.

Per `project_magnitude_eval_collapse_kelly_capped`, the diagnostic
split landed in #212: intent_dist measures policy learning, eval_dist
measures policy + Kelly-cap. Tests asserting on Q-learning success
must use intent_dist; the test was never updated.

Smoke now PASSES with intent_full=0.057 (intent_full=0.866 in the
prior re-run — both above the 0.05 threshold; Q(Full) is clearly
preferred when Kelly cap doesn't suppress it).

ml

10-model ML ensemble for the Foxhunt HFT system, built on Candle v0.9.1.

Models

  • DQN (Rainbow) — deep Q-network with prioritized replay, dueling heads, noisy nets
  • PPO — proximal policy optimization with GAE, LSTM policies, clip-higher
  • TFT — temporal fusion transformer for multi-horizon forecasting
  • Mamba2 — state space model for sequence prediction
  • Liquid Networks — biologically inspired networks for non-stationary data
  • TLOB — transformer-based limit order book analysis
  • KAN — Kolmogorov-Arnold networks
  • xLSTM — extended LSTM architecture
  • TGGN — temporal graph neural network
  • Diffusion — diffusion-based generative model

Key Modules

  • ensemble — model ensemble coordination and confidence aggregation
  • hyperopt — PSO-based hyperparameter optimization with per-model adapters
  • trainers — unified training loops (DQN, PPO, supervised)
  • inferenceInferenceAdapter trait for prediction
  • checkpoint — model checkpointing and restoration
  • evaluation — walk-forward evaluation pipeline
