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.

Building the deployment application

To create the deployment workflow we, once again, use the integrated deployment feature. Strategically inserting the Capture Workflow Start and Capture Workflow End nodes in the workflow, as shown in Figure 13.10, we can isolate the entire sequence of nodes required for processing the test data: the Normalizer node, the Lag Columns component, the Keras Network Executor node, and finally, the Denormalize and Rename component. Additionally, the capture nodes automatically include all the required input models (the trained network and the normalization functions) along with the input and output nodes according to the input and output data tables of the captured workflow segment (Figure 13.12):

Figure 13.12 – The deployment workflow created via integrated deployment

This automatically created workflow is saved in the desired location via the Workflow Writer node and invoked via a Call Workflow node.
