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.

Summary

In this chapter, we dived deep into the inner workings of the LSTM network. We explored both the concepts and mathematical implementation related to these networks, understanding how information is processed in an LSTM cell and using short-term and long-term memory of events. We also saw why the network gets its name, being adept at conserving relevant cell states over very distant timesteps. While we discussed some variants to the architecture, such as the peephole connection, it is seldom seen in most common LSTM candidate scenarios. Although we executed our demonstrations with a simple time series dataset, we highly encourage you to implement this architecture to tackle other problems that you may already be familiar with (such as the IMDB sentiment classification dataset), and compare results with our earlier efforts.
