jgrusewski a26478eca3 fix(ml): cuda_pipeline + trainers infra — CudaSlice throughout
- cuda_pipeline/mod.rs: all Tensor→CudaSlice, DqnGpuData/PpoGpuData GPU-native,
  d2d_subrange helper, build_state_tensor host-interleave + single HtoD
- portfolio_transformer.rs: complete rewrite with GpuLinear + cuBLAS
- trainers/tlob.rs: GpuVarStore + GpuLinear, host-side MSE/MAE
- trainers/tft: StreamTensor trait, MlDevice constructors
- trainers/liquid.rs, mamba2.rs: GpuTensor pairs, f64 loss accumulation
- training/orchestrator.rs: forward_loss(&[f32]) trait interface
- hyperopt/adapters/ppo.rs: MlDevice, PPO::new() constructor
- ml-ppo/lib.rs: fixed cuda_compat→cuda_compile re-export

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;
