jgrusewski a171eaa710 fix: reduce_current_q_stats now just reads graph-computed q_out_buf
The function re-ran 15+ kernels (expected_q, q_mean_center, q_anchoring,
risk_budget, branch_confidence, epistemic_gate, temporal_consistency,
branch_independence, q_attention, graph_message_pass, q_denoise) outside
the graph every step — duplicating work the graph already did.

Now: q_out_buf is populated by graph replay (populate_q_out in aux_child).
reduce_current_q_stats just runs q_stats_kernel (1 kernel) + DtoH sync.
Runs every step since cost is now ~1ms, not ~4s.

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

Usage

use ml::dqn::DQN;
