The lectures in October and November are based on the book: Foundations of machine learning 2nd ed, Mehryar Mohri, Afshin Rostamizadeh, and Ameet Talwalker, 2018.

A gentle introduction to the materials of the first 3 lectures and an overview of probability theory, can be found in chapters 1-6 and 11-12 of the following book: Sanjeev Kulkarni and Gilbert Harman: An Elementary Introduction to Statistical Learning Theory, 2012.

Grading formula

Final grade = 0.35 * [score of homeworks] + 0.35 * [score of colloquium] + 0.3 * [score on the exam] + bonus from quizzes.

All homework questions have the same weight. Each solved extra homework task increases the score of the final exam by 1 point. At the end of the lectures there is a short quiz in which you may earn 0.1 bonus points on the final non-rounded grade.

There is no rounding except for transforming the final grade to the official grade. Arithmetic rounding is used.

Autogrades: if you only need 6/10 on the exam to have the maximal 10/10 for the course, this will be given automatically. This may happen because of extra homework questions and bonuses from quizzes.

Homeworks

Deadline every 2 weeks, before the lecture.

Before 3rd lecture: problems from seminars 1 and 2. Before 5th lecture: problems from seminar 3 and 4. Etc.

Email homeworks to brbauwens-at-gmail.com. Start the subject line with SLT-HW. Results will be here.

Late policy: 1 homework can be submitted at most 24 late without explanations.

Colloquium

Rules and questions from last year.

Date: TBA
