Advanced Deep Learning with Keras

This is the code repository for Advanced Deep Learning with Keras, published by Packt. It contains all the supporting project files necessary to work through the book from start to finish.

About the Book

This book covers advanced deep learning techniques to create successful AI. Using MLPs, CNNs, and RNNs as building blocks to more advanced techniques, you’ll study deep neural network architectures, Autoencoders, Generative Adversarial Networks (GANs), Variational AutoEncoders (VAEs), and Deep Reinforcement Learning (DRL) critical to many cutting-edge AI results.

Instructions and Navigation

All of the code is organized into folders. Each folder starts with a number followed by the application name. For example, chapter2-deep-networks.

The code will look like the following:

def encoder_layer(inputs,
                  filters=16,
                  kernel_size=3,
                  strides=2,
                  activation='relu',
                  instance_norm=True):
"""Builds a generic encoder layer made of Conv2D-IN-LeakyReLU 
IN is optional, LeakyReLU may be replaced by ReLU
"""
conv = Conv2D(filters=filters,
              kernel_size=kernel_size,
              strides=strides,
              padding='same')
