Bases: ashpy.models.convolutional.decoders.Decoder

Fully Convolutional Decoder. Expected input is a feature map.

Examples

  • Direct Usage:
    dummy_generator = FCNNDecoder(
        layer_spec_input_res=(8, 8),
        layer_spec_target_res=(64, 64),
        kernel_size=(5, 5),
        initial_filters=1024,
        filters_cap=16,
        channels=3,
    )
    
    print(dummy_generator(tf.zeros((1, 1, 1, 100))).shape)
    
    (1, 64, 64, 3)
