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.

Enabling GPU execution for neural networks

GPUs operate more slowly than CPUs but have the advantage of performing massive numbers of calculations in parallel. Libraries for the GPU execution of neural training algorithms have been developed and are included in the KNIME Deep Learning – Keras Integration. In this section, we will explore how to speed up the network execution, training, and application with GPU acceleration.

First of all, you need a CUDA-enabled GPU. Then, you need a Python environment that uses the GPU version of the Keras package.

Installing Conda

Conda can be installed easily and for free by going to https://docs.conda.io/projects/conda/en/latest/index.html and downloading the appropriate version for your machine.

First, we set up a GPU Python environment via the dedicated KNIME Preferences page. After that, we can use this Python environment in one of two ways:

  • We set it up as the default environment and all workflows will use it for...
