VEncoder

class aixd.mlmodel.architecture.encoders.VEncoder(in_heads: Dict[str, InHead], out_heads: Dict[str, OutHead], splits: Dict[str, Tuple[int, int]], layer_widths: List[int], latent_dim: int, activation: Module | str)

Bases: Encoder

Encoder module of a conditional variational autoencoder with additional parameters for the latent distribution.

Parameters:

• in_heads (Dict[str, nn.Module]) – Dictionary of input heads, where the keys are strings and the values are PyTorch modules.

• out_heads (Dict[str, nn.Module]) – Dictionary of output heads, where the keys are strings and the values are PyTorch modules.

• splits (Dict[str, Tuple[int, int]]) – Start and end indices for each feature in the input data vectors.

• layer_widths (List[int]) – List of integer values representing the widths of the hidden layers in the encoder.

• latent_dim (int) – Integer value representing the latent dimension of the model.

• activation (str) – String representing the activation function to be used in the hidden layers of the encoder.

Methods

forward
