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.

LSTM memory block

To be able to answer these questions, our network must have several memory cells, where each can store quasi-dependent bits of information regarding the subject of our enquiry, the French emperor Napoleon Bonaparte. In practice, an LSTM unit can have multiple memory cells, each storing different representations from the input sequence. One may store the gender of the subject, another may store the fact that there are multiple subjects, and so on. For the purpose of having clear illustrations, we have taken the liberty of depicting only one memory cell per diagram in this chapter. We do this because understanding the principle behind the workings of one cell will suffice to extrapolate the functioning of a memory block with multiple memory cells. The part of the LSTM that contains all its memory cells is referred to as a memory block. The adaptive information...
