# 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)
- `inference` — `InferenceAdapter` trait for prediction
- `checkpoint` — model checkpointing and restoration
- `evaluation` — walk-forward evaluation pipeline

## Usage

```rust
use ml::dqn::DQN;
use ml::ppo::PpoTrainer;
```
