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.

Configuring the time series integration

In this section, we will give an overview of time series components in KNIME and guide you through the installation of KNIME Python Integration.

Introducing the time series components

The time series components in KNIME implement various preprocessing and modeling tasks that are specific to time series analysis, such as time-aligning the data, aggregating by time granularities, and training a Seasonal Autoregressive Integrated Moving Average (SARIMA) model for forecasting.

You can find the time series components from the Examples space on the KNIME Hub (https://kni.me/s/1415IA5ZFtVXlwg_) and from the EXAMPLES server under 00_Components | Time Series, as shown in the following screenshot:

From both the KNIME Hub and EXAMPLES server, you can drag and drop components into your workflows.
