Codeless Time Series Analysis with KNIME

By: KNIME AG, Corey Weisinger, Maarit Widmann, Daniele Tonini

Overview of this book

This book will take you on a practical journey, teaching you how to implement solutions for many use cases involving time series analysis techniques. This learning journey is organized in a crescendo of difficulty, starting from the easiest yet effective techniques applied to weather forecasting, then introducing ARIMA and its variations, moving on to machine learning for audio signal classification, training deep learning architectures to predict glucose levels and electrical energy demand, and ending with an approach to anomaly detection in IoT. There’s no time series analysis book without a solution for stock price predictions and you’ll find this use case at the end of the book, together with a few more demand prediction use cases that rely on the integration of KNIME Analytics Platform and other external tools. By the end of this time series book, you’ll have learned about popular time series analysis techniques and algorithms, KNIME Analytics Platform, its time series extension, and how to apply both to common use cases.

Summary

In this chapter, you have completed a real-world taxi demand prediction application on the Spark platform.

We have shown you how to work with big data in KNIME and how to prototype big data workflows before accessing a remote cluster. You have, therefore, acquired a toolkit for accessing, preprocessing, and analyzing big data, which enables you with the full computational power of a remote cluster while working from the convenient visual environment in KNIME.

You have worked through training, testing, and deploying a demand prediction application using the random forest algorithm, enabling you with the necessary skills of building demand prediction applications in other fields as well, given that demand prediction is one of the classic applications of time series analysis.

In the next chapter, we extend the demand prediction problem into a multivariate case using an LSTM model.
