Hands-On Neural Networks

By: Leonardo De Marchi, Laura Mitchell

Overview of this book

Neural networks play a very important role in deep learning and artificial intelligence (AI), with applications in a wide variety of domains, right from medical diagnosis, to financial forecasting, and even machine diagnostics. Hands-On Neural Networks is designed to guide you through learning about neural networks in a practical way. The book will get you started by giving you a brief introduction to perceptron networks. You will then gain insights into machine learning and also understand what the future of AI could look like. Next, you will study how embeddings can be used to process textual data and the role of long short-term memory networks (LSTMs) in helping you solve common natural language processing (NLP) problems. The later chapters will demonstrate how you can implement advanced concepts including transfer learning, generative adversarial networks (GANs), autoencoders, and reinforcement learning. Finally, you can look forward to further content on the latest advancements in the field of neural networks. By the end of this book, you will have the skills you need to build, train, and optimize your own neural network model that can be used to provide predictable solutions.

CNNs in Keras

To showcase the CNN architecture, we will use a classic classification problem: the Modified National Institute of Standards and Technology (MNIST) dataset. The MNIST database is a set of handwritten digits composed of 60,000 datapoints for testing and 10,000 for training.

Keras provides ready to use datasets, including the MNIST dataset. The resolution of the images is only 28 x 28 pixels and is black and white, therefore, the computational cost to train the network is relatively low.

We will now illustrate how to create a CNN in Keras to solve a classification task using the MNIST dataset and achieve human-like performance.

Loading the data

First, we need to load the data and the libraries required to build...
