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.

Movie Reviews Sentiment Analysis Using Recurrent Neural Networks

A recurrent neural network is a neural model in which a bidirectional flow of information is present. In other words, while the propagation of signals in feedforward networks takes place only in a continuous manner in one direction, from inputs to outputs, recurrent networks are different. In recurrent networks, this propagation can also derive from a neural layer following the current one, between neurons belonging to the same layer, or even between a neuron and itself. The set of natural language processing techniques, text analysis, and computational linguistics that are used to identify and extract subjective information in written or spoken text sources is called sentiment analysis. In this chapter, a recurrent neural network is used to classify sentiment in movie reviews.

The following topics are covered in...
