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.

Chapter 13: GPU Accelerated Model for Multivariate Forecasting

Time series analysis models can become quite large, and their training can become computationally expensive. This is especially the case when moving from univariate to multivariate time series predictions. In some of these cases, GPUs can be used to accelerate the process.

So far, we have described univariate time series models, relying on past values of one time series to predict the future value of the same time series. Often, real-world problems and data are not that simple. If two time series correlate, the value of a variable at a given point in time can depend on the past values of the same variable and the past values of other variables from other series. Integrating such multiple variables into the input or output of the model is called multivariate time series analysis. A model for multivariate predictions can output just one value, which is the next value of one of the time series, or multiple values, which...
