Professor Riedl was a pioneer in the field of recommender systems. These are the information systems that “recommend” an item, such as a book or movie, based on previous choices. Professor Riedl was internationally recognized for this work and received numerous awards. He had been using MSI resources for the further development of LensKit, a toolkit his group has created for developing and testing recommender algorithms.
An obituary of Professor Riedl appears on the College of Science and Engineering website.
MSI staff extend their deepest condolences to Professor Riedl’s family, friends, and colleagues.
