jgrusewski 5c8dc537f0 refactor: fully VRAM-proportional hyperopt bounds — zero hardcoded tiers
All search space bounds now derived from HardwareBudget methods:
- batch: budget.max_batch_size()
- hidden_dim: budget.max_hidden_dim_base_full()
- dueling/branch: proportional to max_hidden (50%/25%)
- buffer: 15% VRAM / 120 bytes per entry
- atoms: 5% VRAM / per-atom tensor cost
- accum: proportional to VRAM / 10GB

Removed small_gpu/large_gpu boolean tiers entirely. A 24GB GPU now
gets bounds between 4GB and 80GB values, not arbitrarily bucketed.

Phase Fast fixed bounds (lo==hi) still skipped — never modified.

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
