Denoising autoencoder in Keras

Now let's build the same denoising autoencoder in Keras.

As Keras takes care of feeding the training set by batch size, we create a noisy training set to feed as input for our model:

X_train_noisy = add_noise(X_train)

The complete code for the DAE in Keras is provided in the notebook ch-10_AutoEncoders_TF_and_Keras.

The DAE Keras model looks like the following:

Layer (type)                 Output Shape              Param #
