There has been a lot of talk about the Internet of Things lately: intelligent households, smart cities, wearable technology, manufacturing sensors, and more.
The Internet of Things poses a great challenge for data analysts, on the one hand because of the very large amounts of data created over time; and on the other because of the algorithms that make the sensor-equipped object (house or city) capable of learning, and therefore smarter.
We decided to take up this challenge and put KNIME to work to:
This project focuses on the data from a bike share system in Washington, DC, called Capital Bikeshare. Each Capital Bikeshare’s bike carries a sensor, which sends the current real-time bike location to a central repository. All historical data is public and has been downloaded and used for this study.
The downloaded data has also been enriched with topology, elevation, local weather, holiday schedules, traffic situations, business locations, tourist attractions, and other types of information widely available on the internet via web or REST services. After transformation and the application of machine learning algorithms for time series prediction, an optimized alarm system can give us a warning when bike restocking is necessary at a given bike station in the next hour.
Dr. Rosaria Silipo (LinkedIn) is not only an expert in data mining, machine learning, reporting, and data warehousing, she has become a recognized expert on the KNIME data mining engine, about which she has published three books: KNIME Beginner’s Luck, The KNIME Cookbook, and The KNIME Booklet for SAS Users. Previously Dr. Silipo worked as a freelance data analyst for many companies throughout Europe. She has also led the SAS development group at Viseca (Zürich), implemented the speech-to-text and text-to-speech interfaces in C# at Spoken Translation (Berkeley, California), and developed a number of speech recognition engines in different languages at Nuance Communications (Menlo Park, California). Dr. Silipo gained her doctorate in biomedical engineering in 1996 from the University of Florence, Italy.
