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.

Deploying an FFNN-based alarm system

In this section, you will deploy the previously trained alarm system within a dedicated workflow. This deployment workflow will need the following:

  • The ability to accept new data in the same shape and format as the original data
  • The normalization model to apply to the new data
  • The same preprocessing steps as for the testing part of the workflow
  • The trained FFNN model
  • The Keras Network Executor node
  • The same postprocessing of the results to create the alarm system

We can do this manually by using the workflow shown in Figure 9.10. However, we can also create the deployment workflow automatically by replicating the testing part of that workflow. KNIME’s Integrated Deployment can do this and consists of three nodes: the Capture Workflow Start node, the Capture Workflow End node, and the Workflow Writer node.

The Capture Workflow Start and Capture Workflow End nodes are placed at the beginning and the end...
