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.

Predicting taxi demand in NYC

Taxi demand prediction in large cities contributes to the satisfaction of a wide audience. The taxi fleet will be working more effectively, the customers will get their rides on time, and even city planners can benefit from knowing the taxi rush hours throughout the day and week.

We demonstrate the taxi demand prediction use case with the NYC taxi dataset (available at https://www1.nyc.gov/site/tlc/about/tlc-trip-record-data.page) provided by the NYC Taxi and Limousine Commission (TLC). The data contains altogether over 1 billion taxi trips from January 2009 forward. For each taxi trip, detailed information is recorded, such as the pick-up/drop-off date, time, and location, the type of the taxi (yellow/green/for-hire vehicle), passenger count, and fare.

The demand prediction means concretely predicting the expected count of taxi trips in the next hour based on the trip counts in the previous hours. The goal is to train the model on data from one...
