Hands-On Neural Networks with Keras

By: Niloy Purkait

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.

Designing a GAN in Keras

For this exercise, suppose you were part of a research team working for a large automobile manufacturer. Your boss wants you to come up with a way to generate synthetic designs for cars, to systematically inspire the design team. You have heard all the hype about GANs and have decided to investigate whether they can be used for the task at hand. To do this, you want to first do a proof of concept, so you quickly get a hold of some low-resolution pictures of cars and design a basic GAN in Keras to see whether the network is at least able to recreate the general morphology of cars. Once you can establish this, you can convince your manager to invest in a few Titan x GUPs for the office, get some higher-resolution data, and develop some more complex architectures. So, let's start by implementing this proof of concept by first getting our hands on some...
