I was able to get insights of machine learning techniques from a mathematical view. I would definitely take another class from him. One weakness of this class is the organization and lecture notes of this class which were provided by the previous professor. Other than that, the class was awesome.

His philosophy with exams was to make them pretty hard, but grade them leniently. He is very accessible and understanding.","source_url":"https://www.ratemyprofessors.com/professor/2911773","quality_rating":2.0,"difficulty_rating":4.0},{"observed_at":"2026-09-07 16:06:27.124670+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTQxMzAzMzU4","source_instructor_id":"rmp:1781624","instructor_name":"Sebastien Roch","course_label":"MATH535","course_id":"MATH 535","course_uid":"course_85a2851be919e3db46f0fbc1","review_date":"2025-05-16 14:45:19 +0000 UTC","comment":"All MATH535 lecture material comes from an online textbook written by Dr. Roch himself. Attendance is measured using TopHat (full credit for attending at least half the classes). He's a pretty good lecturer, focusing on the most important topics and leaving time for questions.
