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.

The importance of predicting the weather

Forecasting the weather is something people have been doing for nearly forever, with a huge amount of different approaches. For this chapter, we use humidity as an accessible and relatable example. The most sophisticated modern methods for forecasting the weather, temperature, and humidity use complicated physical simulations alongside data science techniques, and we can’t really hope to outperform them for long-term forecasts.

Despite this, we will see that with a concisely defined purpose, even the simplest models can prove useful. In this chapter, we will focus on generating forecasts only a few units (in our case, hours) into the future. If the humidity is in the process of spiking, we will want to bring our sensors, and whatever they are attached to, inside before it rains. In later chapters, we will extend the forecast horizon to predict days or weeks into the future.
