jgrusewski 410ede2ad7 fix(ml): OOM guard on CPU PER fallback, clippy cleanup, PPO recurrent test fixes
- Add 4 GB pre-flight memory check in try_gpu_prioritized_with_fallback
  before attempting CPU PER fallback (prevents system OOM on absurd capacity)
- GPU pre-flight already rejects oversized buffers; CPU fallback was unguarded
- Fix integration test: assert Err for 500M capacity instead of unwrap
- Fix PPO recurrent tests: TradingAction → FactoredAction, num_actions 3/5 → 45
- Clippy: wildcard match arms → explicit variants, add missing else clause

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;
