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.

Generative adversarial networks

Generative adversarial networks (GANs) are a class of networks that were introduced by Ian Goodfellow in 2014. In GANs, two neural networks play off against one another as adversaries in an actor-critic model, where one is the creator and the other is the scrutinizer. The creator, referred to as the generator network, tries to create samples that will fool the scrutinizer, the discriminator network. These two increasingly play off against one another, with the generator network creating increasingly believable samples and the discriminator network getting increasingly good at spotting the samples. In summary:

  • The generator tries to maximize the probability of the discriminator passing its outputs as real, not generated
  • The discriminator guides the generator to create ever more realistic samples

All in all, this process is represented as follows...
