Overview of this book

New experiences can be intimidating, but not this one! This beginner’s guide to deep learning is here to help you explore deep learning from scratch with Keras, and be on your way to training your first ever neural networks. What sets Keras apart from other deep learning frameworks is its simplicity. With over two hundred thousand users, Keras has a stronger adoption in industry and the research community than any other deep learning framework. The Deep Learning with Keras Workshop starts by introducing you to the fundamental concepts of machine learning using the scikit-learn package. After learning how to perform the linear transformations that are necessary for building neural networks, you'll build your first neural network with the Keras library. As you advance, you'll learn how to build multi-layer neural networks and recognize when your model is underfitting or overfitting to the training data. With the help of practical exercises, you’ll learn to use cross-validation techniques to evaluate your models and then choose the optimal hyperparameters to fine-tune their performance. Finally, you’ll explore recurrent neural networks and learn how to train them to predict values in sequential data. By the end of this book, you'll have developed the skills you need to confidently train your own neural network models.

Preface

Introduction

In the previous chapter, you learned about the mathematics of neural networks, including linear transformations with scalars, vectors, matrices, and tensors. Then, you implemented your first neural network using Keras by building a logistic regression model to classify users of a website into those who will purchase from the website and those who will not.

In this chapter, you will extend your knowledge of building neural networks using Keras. This chapter covers the basics of deep learning and will provide you with the necessary foundations so that you can build highly complex neural network architectures. We will start by extending the logistic regression model to a simple single-layer neural network and then proceed to more complicated neural networks with multiple hidden layers.

In this process, you will learn about the underlying basic concepts of neural networks, including forward propagation for making predictions, computing loss, backpropagation for computing...
