}

Neural diffusion backend configuration.

Controls the candle-based neural score network that learns joint distributions from training data for the neural and hybrid diffusion backends.

Fields

hidden_dims: Vec<usize>

Hidden layer dimensions for the score network MLP.

timestep_embed_dim: usize

Dimensionality of the timestep embedding.

learning_rate: f64

Learning rate for training.

training_epochs: usize

Number of training epochs.

batch_size: usize

Training batch size.

hybrid_weight: f64

Blend weight for hybrid mode (0.0 = all statistical, 1.0 = all neural).

hybrid_strategy: String

Hybrid blending strategy: “weighted_average”, “column_select”, “threshold”.

neural_columns: Vec<String>

Columns to apply neural generation to (empty = all numeric columns).

checkpoint_path: Option<String>

v4.4.0+ Optional path to a pre-trained score-network checkpoint (.safetensors). When set, the orchestrator loads the checkpoint instead of training from the first batch — useful for long-running production deployments where training cost dominates per-run cost. When empty, the orchestrator trains on the first generated JE amounts.
