Hands-On Artificial Intelligence for IoT - Second Edition

By: Amita Kapoor

Overview of this book

There are many applications that use data science and analytics to gain insights from terabytes of data. These apps, however, do not address the challenge of continually discovering patterns for IoT data. In Hands-On Artificial Intelligence for IoT, we cover various aspects of artificial intelligence (AI) and its implementation to make your IoT solutions smarter. This book starts by covering the process of gathering and preprocessing IoT data gathered from distributed sources. You will learn different AI techniques such as machine learning, deep learning, reinforcement learning, and natural language processing to build smart IoT systems. You will also leverage the power of AI to handle real-time data coming from wearable devices. As you progress through the book, techniques for building models that work with different kinds of data generated and consumed by IoT devices such as time series, images, and audio will be covered. Useful case studies on four major application areas of IoT solutions are a key focal point of this book. In the concluding chapters, you will leverage the power of widely used Python libraries, TensorFlow and Keras, to build different kinds of smart AI models. By the end of this book, you will be able to build smart AI-powered IoT apps with confidence.

Multilayered perceptrons for regression and classification


In the last section, you learned about a single artificial neuron and used it to predict the energy output. If we compare it with the linear regression result of Chapter 3, Machine Learning for IoT, we can see that though the single neuron did a good job, it was not as good as linear regression. The single neuron architecture had an MSE value of 0.078 on the validation dataset as compared 0.01 of linear regression. Can we make it better, with maybe more epochs, or different learning rate, or perhaps more single neurons. Unfortunately not, single neurons can solve only linearly separable problems, for example, they can provide a solution only if there exists a straight line separating the classes/decision.

Note

The network with a single layer of neurons is called simple perceptron. The perceptron model was given by Rosenblatt in 1958 (http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.335.3398&rep=rep1&type=pdf...
