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.

Glucose prediction and the glucose dataset

In this chapter, we will look at glucose prediction to learn how to generate time series forecasts through a neural network model. This use case starts by predicting a physical variable that triggers a chain of actions. The physical variable could be anything that can be measured via a sensor: temperature, electricity, or, in this case, blood glucose level. This chain of actions ranges from a simple warning email to an alarm that shuts down the entire system and has numerous applications in manufacturing and machine maintenance. In the upcoming sections, we will review the dataset and techniques we will use to develop this alarm system, as well as why it is needed.

Glucose prediction

Diabetes is an increasingly common disease that affects your ability to convert carbohydrates into energy. Food is broken down into glucose and released into your bloodstream. From here, a hormone called insulin moves the glucose to the cells that need it...
