The key parameters for the toy latent-action and forward models are:
- K (latent codebook size): Number of K-means displacement clusters; set to 4 even though movement plus no-op yields five distinct observed displacements.
- GRID: Side length of the square grid world; set to 8.
- horizon: Number of steps per generated trajectory; set to 15 for training and reused for rollouts.
- hidden_layer_sizes: Width and depth of the forward-model MLP; set to (32, 32).
- max_iter: Maximum training iterations for the MLP; set to 150.
- random_state: Seed for -means and the MLP; set to 0 for reproducibility.
- early_stopping: Whether the MLP holds out a validation split to stop early; set to True.
