Next, we continue our journey designing the discriminator module, which will be responsible for telling the real images from the fake ones supplied by the generator module we just designed. The concept behind the architecture is quite similar to that of the generator, with some key differences. The discriminator network receives images of a 32 x 32 x 3 dimension, which it then transforms into various representations as information propagates through deeper layers, until the dense classification layer is reached, equipped with one neuron and a sigmoid activation function. It has one neuron, since we are dealing with the binary classification task of distinguishing fake from real. The sigmoid function ensures a probabilistic output between 0 and 1, indicating how fake or real the network thinks a given image may be. Do also note the inclusion of...

Overview of this book
Neural networks are used to solve a wide range of problems in different areas of AI and deep learning.
Hands-On Neural Networks with Keras will start with teaching you about the core concepts of neural networks. You will delve into combining different neural network models and work with real-world use cases, including computer vision, natural language understanding, synthetic data generation, and many more. Moving on, you will become well versed with convolutional neural networks (CNNs), recurrent neural networks (RNNs), long short-term memory (LSTM) networks, autoencoders, and generative adversarial networks (GANs) using real-world training datasets. We will examine how to use CNNs for image recognition, how to use reinforcement learning agents, and many more. We will dive into the specific architectures of various networks and then implement each of them in a hands-on manner using industry-grade frameworks.
By the end of this book, you will be highly familiar with all prominent deep learning models and frameworks, and the options you have when applying deep learning to real-world scenarios and embedding artificial intelligence as the core fabric of your organization.
