Simplified reimplementation of TinyRecursiveModels using MLX.

1. Setup the environment

   uv sync
   source .venv/bin/activate

2. Adjust model config in train.py

   @dataclass
   class ModelConfig:
       in_channels: int
       depth: int
       dim: int
       heads: int
       patch_size: tuple
       n_outputs: int
       pool: str = "cls" # mean or cls
       n: int = 6  # latent steps
       T: int = 3  # deep steps
       halt_max_steps: int = 8  # maximum supervision steps
       halt_exploration_prob: float = 0.2  # exploratory q probability
       halt_follow_q: bool = True  # follow q (True) or max steps (False)

3. Train on MNIST or CIFAR-10 (see python train.py --help):

   python train.py --dataset mnist
   python train.py --dataset cifar10

• Hyperparams are currently hardcoded for faster experimentation.
• Only MNIST and CIFAR-10 are supported at the moment.
• uv handles virtual environment creation automatically.
