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.

Chapter 6: Humidity Forecasting with Classical Methods

In this chapter, we will build the first forecasting model ready for deployment, looking at how data can be recorded from sensors attached to an Arduino controller.

You’ll learn how KNIME Analytics Platform, as well as KNIME Server, can connect to sensors via REST endpoints, the basics of time series data cleaning and pre-processing, the different options for data granularity levels, and several classic and easy-to-use models that can be used for forecasting. Finally, we’ll look at some simple ways the model can be deployed for real-world applications with KNIME, such as writing model predictions to databases or saving trained models and workflows for later use.

We will cover the following main topics in the chapter:

  • The importance of predicting the weather
  • Streaming humidity data from an Arduino sensor
  • Resampling and granularity
  • Training and deployment
