Hands-On Artificial Intelligence for IoT - Second Edition

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.

CSV format


Comma-separated value (CSV) files are the most popular formats for storing tabular data generated by IoT systems. In a .csv file, the values of the records are stored in plain-text rows, with each row containing the values of the fields separated by a separator. The separator is a comma by default but can be configured to be any other character. In this section, we will learn how to use data from CSV files with Python's csv, numpy, and pandas modules. We will use the household_power_consumption data file. The file can be downloaded from the following GitHub link: https://github.com/ahanse/machlearning/blob/master/household_power_consumption.csv. To access the data files, we define the following variables:

data_folder = '../../data/household_power_consumption' 
data_file = 'household_power_consumption.csv'

Generally, to quickly read the data from CSV files, use the Python csv module; however, if the data needs to be interpreted as a mix of date, and numeric data fields, it's better...
