# --- Data Paths ---
# These paths point to the HDF5 files produced by the chebnet_conditional_setup.py script.
data:
  # Path to the HDF5 file containing the dynamic, frame-by-frame pooled embeddings.
  embeddings_h5_path: "latent_reps/pooled_embeddings.h5"
  
  # Path to the HDF5 file containing the static reference conditioners (z_ref).
  conditioners_h5_path: "latent_reps/reference_conditioners.h5"
  
  # Template for the group name within the HDF5 files. '{}' is replaced by the system ID.

# --- Model & Training Parameters ---
parameters:
  # --- Augmentation Control ---
  # If true, the script will load the conditioner ensemble and randomly sample from it during training.
  # This makes the model more robust to noise in the conditioner.
