The Applied Artificial Intelligence Workshop

By: Anthony So, William So, Zsolt Nagy

Overview of this book

You already know that artificial intelligence (AI) and machine learning (ML) are present in many of the tools you use in your daily routine. But do you want to be able to create your own AI and ML models and develop your skills in these domains to kickstart your AI career? The Applied Artificial Intelligence Workshop gets you started with applying AI with the help of practical exercises and useful examples, all put together cleverly to help you gain the skills to transform your career. The book begins by teaching you how to predict outcomes using regression. You will then learn how to classify data using techniques such as k-nearest neighbor (KNN) and support vector machine (SVM) classifiers. As you progress, you’ll explore various decision trees by learning how to build a reliable decision tree model that can help your company find cars that clients are likely to buy. The final chapters will introduce you to deep learning and neural networks. Through various activities, such as predicting stock prices and recognizing handwritten digits, you’ll learn how to train and implement convolutional neural networks (CNNs) and recurrent neural networks (RNNs). By the end of this applied AI book, you’ll have learned how to predict outcomes and train neural networks and be able to use various techniques to develop AI and ML models.

Preface

Artificial Neurons

Artificial Neural Networks (ANNs), as the name implies, try to replicate how a human brain works, and more specifically how neurons work.

A neuron is a cell in the brain that communicates with other cells via electrical signals. Neurons can respond to stimuli such as sound, light, and touch. They can also trigger actions such as muscle contractions. On average, a human brain contains 10 to 20 billion neurons. That's a pretty huge network, right? This is the reason why humans can achieve so many amazing things. This is also why researchers have tried to emulate how the brain operates and in doing so created ANNs.

ANNs are composed of multiple artificial neurons that connect to each other and form a network. An artificial neuron is simply a processing unit that performs mathematical operations on some inputs (x1, x2, …, xn) and returns the final results (y) to the next unit, as shown here:
