Machine Learning for Streaming Data with Python

By: Joos Korstanje

Overview of this book

Streaming data is the new top technology to watch out for in the field of data science and machine learning. As business needs become more demanding, many use cases require real-time analysis as well as real-time machine learning. This book will help you to get up to speed with data analytics for streaming data and focus strongly on adapting machine learning and other analytics to the case of streaming data. You will first learn about the architecture for streaming and real-time machine learning. Next, you will look at the state-of-the-art frameworks for streaming data like River. Later chapters will focus on various industrial use cases for streaming data like Online Anomaly Detection and others. As you progress, you will discover various challenges and learn how to mitigate them. In addition to this, you will learn best practices that will help you use streaming data to generate real-time insights. By the end of this book, you will have gained the confidence you need to stream data in your machine learning models.

Summary

In this chapter, you have learned the basics of online machine learning in both theory and practice. You have seen different types of online machine learning, including incremental, adaptive, and reinforcement learning.

You have seen a number of advantages and disadvantages of online machine learning. Among other reasons, you may be almost obliged to refer to online methods if quick relearning is required. A disadvantage is that fewer methods are commonly available, as batch learning remains the industry standard for now.

Finally, you have started practicing and implementing online machine learning through a Python example on the well-known iris dataset.

In the coming chapter, you'll go much deeper into online machine learning, focusing on anomaly detection. You'll see how machine learning can be used to replace the fixed rule alerting system that was built in previous chapters. In the chapters after that, you'll learn more about online classification...
