jgrusewski c3ea0e57d1 feat(generalization): domain randomization — per-epoch jitter on sim params
Prevents memorization of fixed simulation parameters that exist only
in training. Each epoch randomizes:
- tx_cost_multiplier: U[0.5, 2.5] (was fixed 1.0)
- spread: U[0.5x, 3.0x] base spread
- fill_ioc_prob: U[0.65, 0.95] (was fixed 0.85)
- fill_limit_min/max: randomized ranges
- spread_cost: U[0.3, 0.8] fraction
- Episode starts: ±25% stride jitter (was deterministic)
- Episode length: ±25% base (was fixed)

Controlled by enable_domain_randomization flag (default: true).

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;
use ml::ppo::PpoTrainer;
