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.

Chapter 4: Time Series Visualization

In a time series analysis application, visualization often follows data preprocessing, which we introduced in the previous chapter. Data preprocessing cleans the data and puts it into the right size and level of detail for effective visualization and modeling.

This chapter is dedicated to time series visualization to see the kind of time series we are dealing with. It will provide an exploration of the most common visualization techniques to visually represent and display time series data: from a classic line plot to a lag plot; from a seasonal plot to a box plot.

By visualizing time series, we can gain first insights into the data and the analytical problem and increase its accessibility and understandability. Visual data exploration of time series can thus be the goal of the analysis, or it can justify further preprocessing steps and selected analysis methods.

In this chapter, we will introduce visualization techniques on energy consumption...
