Hands-On Artificial Intelligence for Beginners

By: Patrick D. Smith, David Dindi

Overview of this book

Virtual Assistants, such as Alexa and Siri, process our requests, Google's cars have started to read addresses, and Amazon's prices and Netflix's recommended videos are decided by AI. Artificial Intelligence is one of the most exciting technologies and is becoming increasingly significant in the modern world. Hands-On Artificial Intelligence for Beginners will teach you what Artificial Intelligence is and how to design and build intelligent applications. This book will teach you to harness packages such as TensorFlow in order to create powerful AI systems. You will begin with reviewing the recent changes in AI and learning how artificial neural networks (ANNs) have enabled more intelligent AI. You'll explore feedforward, recurrent, convolutional, and generative neural networks (FFNNs, RNNs, CNNs, and GNNs), as well as reinforcement learning methods. In the concluding chapters, you'll learn how to implement these methods for a variety of tasks, such as generating text for chatbots, and playing board and video games. By the end of this book, you will be able to understand exactly what you need to consider when optimizing ANNs and how to deploy and maintain AI applications.

Memory units – LSTMs and GRUs

While regular RNNs can theoretically ingest information from long sequences, such as full documents, they are limited in how far back they can look to learn information. To overcome this, researchers have developed variants on the traditional RNN that utilize a unit called a memory cell, which helps the network remember important information. They were developed as a means to solve the vanishing gradient problem that occurs with traditional RNN models. There are two main variations of RNN that utilize memory cell architectures, known as the GRU and the LSTM. These architectures are the most widely used RNN architectures, so we'll pay some what attention to their mechanics.
