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.

Statistics of character modeling

We often distinguish words and numbers as being in different realms. As it happens, they are not so far apart. Everything can be deconstructed using the universal language of mathematics. This is quite a fortunate property of our reality, not just for the pleasure of modeling statistical distributions over sequences of characters. However, since we are on the topic, we will go ahead and define the concept of language models. In essence, language models follow Bayesian logic that relates the probability of posterior events (or tokens to come) as a function of prior occurrences (tokens that came). With such an assumption, we are able to construct a feature space corresponding to the statistical distribution of words over a period of time. The RNNs we will build shortly will each construct a unique feature space of probability distributions. Then...
