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 a Gradient Boosted Forest

To deploy the classification model and preprocessing along with it, we’ll use KNIME Analytics Platform’s Integrated Deployment feature. As you will see in the following figure, the preprocessing of the test set along with the Gradient Boosted Trees Predictor node lie directly between the Capture Workflow Start and Capture Workflow End nodes. Any nodes between the capture start and end will be combined into an automatically generated deployment workflow as we will see.

In the following figure, we see how the Integrated Deployment nodes surround the preprocessing and model prediction.

Figure 8.15 – Captured portion of training workflow

Looking at Figure 8.15, you’ll notice that the trained Gradient Boosted Forest model that plugs into the Gradient Boosted Trees Predictor node is also required to execute this section of the training workflow. KNIME’s Integrated Deployment functionality...
