Professor Babinec did a wonderful job of leading us through this material. It is obvious that he has a passion for this subject. His breadth of knowledge of and experience with cluster analysis added significantly to the course. He gave very helpful answers in the discussion forum! Anuja, our teaching assistant, was very supportive throughout the course as well. The course material was challenging but fulfilling, helping us appreciate the subtleties of cluster analysis rather than thoughtlessly plunge ahead. In summary, this was a very satisfying and useful course.
