jgrusewski 74f63f80b2 perf: attention + IQL block 32→256 (occupancy 3.1%→25%)
Same optimization pattern as IQN: increase block size from 32 (1 warp)
to 256 (8 warps) for all attention and IQL kernels.

Attention (forward + backward):
- Loop strides 32→256, shared_concat dynamic shmem
- Added bf16_block_max/bf16_block_sum for 8-warp reduction
- Replaces warp-only shuffle with shared memory cross-warp reduce

IQL (forward+loss, backward, forward-only):
- Loop strides 32→256, added iql_bf16_block_sum
- grad_norm + adam kernels already at 256, unchanged

Expected: ~15-20ms/step savings from attention+IQL combined.

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
