_calculate_conv_output_size()

Calculate the output size after all convolutional layers for the linear bottleneck.

encode(x)

Encode input to latent space with skip connections.

decode(latent, skip_connections, encoded_shape)

Decode from latent space to image with skip connections.

forward(x)

Forward pass - returns latent representation for anomaly detection.

reconstruct(x)

Full reconstruction for evaluation and anomaly detection.

train_step(batch)

This function contains the logic for a single training step.

Parameters:

batch (tuple) – A tuple containing the two values the loss function

Returns:

Current loss value – Dictionary containing the loss value for the current batch.

Return type:

dict

static to_tensor(data_dict)

Convert structured data to tensor format.
