AI Blueprints

By: Dr. Joshua Eckroth, Eric Schoen

Overview of this book

AI Blueprints gives you a working framework and the techniques to build your own successful AI business applications. You’ll learn across six business scenarios how AI can solve critical challenges with state-of-the-art AI software libraries and a well thought out workflow. Along the way you’ll discover the practical techniques to build AI business applications from first design to full coding and deployment. The AI blueprints in this book solve key business scenarios. The first blueprint uses AI to find solutions for building plans for cloud computing that are on-time and under budget. The second blueprint involves an AI system that continuously monitors social media to gauge public feeling about a topic of interest - such as self-driving cars. You’ll learn how to approach AI business problems and apply blueprints that can ensure success. The next AI scenario shows you how to approach the problem of creating a recommendation engine and monitoring how those recommendations perform. The fourth blueprint shows you how to use deep learning to find your business logo in social media photos and assess how people interact with your products. Learn the practical techniques involved and how to apply these blueprints intelligently. The fifth blueprint is about how to best design a ‘trending now’ section on your website, much like the one we know from Twitter. The sixth blueprint shows how to create helpful chatbots so that an AI system can understand customers’ questions and answer them with relevant responses. This book continuously demonstrates a working framework and strategy for building AI business applications. Along the way, you’ll also learn how to prepare for future advances in AI. You’ll gain a workflow and a toolbox of patterns and techniques so that you can create your own smart code.

Neural networks and deep learning


Neural networks, also known as artificial neural networks, are an ML paradigm inspired by animal neurons. A neural network consists of many nodes, playing the role of neurons, connected via edges, playing the role of synaptic connections. Typically, the neurons are arranged in layers, with each layer fully connected to the next. The first and last layers are input and output layers, respectively. Inputs may be continuous (but often normalized to [-1, 1]) or binary, while outputs are typically binary or probabilities. The network is trained by repeatedly examining the training set. Each repetition on the full training set is called an "epoch." During each epoch, the weights on each edge are slightly adjusted in order to reduce the prediction error for the next epoch. We must decide when to stop training, that is, how many epochs to execute. The resulting learned "model" consists of the network topology as well as the various weights.

Each neuron has a set...
