Overview of this book

Keras 2.x Projects explains how to leverage the power of Keras to build and train state-of-the-art deep learning models through a series of practical projects that look at a range of real-world application areas. To begin with, you will quickly set up a deep learning environment by installing the Keras library. Through each of the projects, you will explore and learn the advanced concepts of deep learning and will learn how to compute and run your deep learning models using the advanced offerings of Keras. You will train fully-connected multilayer networks, convolutional neural networks, recurrent neural networks, autoencoders and generative adversarial networks using real-world training datasets. The projects you will undertake are all based on real-world scenarios of all complexity levels, covering topics such as language recognition, stock volatility, energy consumption prediction, faster object classification for self-driving vehicles, and more. By the end of this book, you will be well versed with deep learning and its implementation with Keras. You will have all the knowledge you need to train your own deep learning models to solve different kinds of problems.

Multilayer neural networks

The term multilayer neural networks denotes neural networks composed of many hidden levels (at least two) organized hierarchically. Hierarchical organization allows you to share and reuse information. Along the hierarchy, you can select specific features and discard unnecessary details in order to maximize the invariance. In multilevel machine learning, the deeper levels take inputs from the outputs of previous layers and perform more transformations and abstractions on them. This management of learning levels is inspired by the way in which a mammalian brain processes information and learns, responding to external stimuli. The following diagram shows a generic architecture of a multilayer neural network (with two hidden layers):

Multilayer neural networks have applications in many fields—speech recognition systems, pattern search, and image...
