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.

Understanding peephole connections

The point behind peephole connections is the need to capture the information of time lags. In other words, we wish to include the information conveyed by time intervals between sub-patterns of sequences in our modeling efforts. This is relevant not only for certain language processing tasks (such as speech recognition), but also for numerous other tasks ranging from machine motor control to maintaining elaborate rhythms in computer-generated music. Previous approaches to tasks such as speech recognition employed the use of Hidden Markov Models (HMMs). These are essentially statistical models that estimate the probability of a set of observations based on the sequence of hidden state transitions. In the case of speech processing, observations are defined as segments of digital signals corresponding to speech, while Markov hidden states are the...
