class ashpy.models.fc.autoencoders.Autoencoder(hidden_units, encoding_dimension, output_shape)

Bases: tensorflow.python.keras.engine.training.Model

Primitive Model for all fully connected autoencoders.

Examples

• Direct Usage:

  autoencoder = Autoencoder(
      hidden_units=[256,128,64],
      encoding_dimension=100,
      output_shape=55
  )
  
  encoding, reconstruction = autoencoder(tf.zeros((1, 55)))
  print(encoding.shape)
  print(reconstruction.shape)

__init__(hidden_units, encoding_dimension, output_shape)

Instantiate the Decoder.

Parameters:

• hidden_units (tuple of int) – Number of units per hidden layer.
• encoding_dimension (int) – encoding dimension.
• output_shape (int) – output shape, usual equal to the input shape.

Returns:

None

call(inputs, training=True)

Execute the model on input data.

Parameters:

• inputs (tf.Tensor) – Input tensors.
• training (bool) – Training flag.

Returns:

(encoding, reconstruction) – Pair of tensors.
