AutoEncoders can have a lossy intermediate representation, also known as compressed representation. Such dimensionality reduction is useful in a variety of cases where lossless compression of image data exists. Thus, we can say that the encoding part of AutoEncoder encodes a dense representation of the data. Here we will use the TensorFlow Subclass API to define custom layers for the encoder and decoder.
We then expand to define a custom model that uses our previously defined custom layers to generate the AutoEn model coder. The call function is overridden, which is a direct pass when the data is made available to the model object. Notice the decorator function. This ensures that the function is executed in a graph, which speeds up our execution.
The next block of code prepares the dataset and prepares the data to be passed to the preprocessing pipeline before training AutoEncoder.
It is recommended to use TensorFlow to quickly obtain mixed batch tensor slices from a training dataset. The following code block demonstrates the use of tf.data and also defines hyperparameters for training the AutoEncoder model.
We have met all the prerequisites to train our AutoEncoder model! All we have left to do is — it is to define an AutoEncoder object and compile the optimizer and lossy model before calling model.train for it for the hyperparameters defined above. Voila! You can see loss reduction and AutoEncoder improving your performance!
