jgrusewski 075ed8ba4f fix: disable selectivity+denoise outside graph — CUfunction shared with graphed children
step_denoise_adam uses adam_update_kernel + grad_norm_finalize_kernel UNGRAPHED
after child graph replays. Same CUfunctions are captured in adam_child and
forward_child. On Hopper, launching a captured CUfunction ungraphed corrupts
graph kernel state → 3100ms adam_child replay on next step.

Fix: skip selectivity+denoise ungraphed training. These are auxiliary optimizers
with non-fatal error handling. To re-enable: load separate CUfunction instances
for ungraphed paths or move into child graphs.

Expected: adam drops from 3100ms to ~30ms. Epoch from ~690s to ~60s.

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
