課程概述 |
Caveat: This is a theory course. ALL of the homework and exam problems ask you to work out mathematical proofs.
This is a course on optimization for machine learning. Therefore, we will focus on the black-box approach and first-order methods. We will NOT study classical topics such as linear programming and semi-definite programming.
This course consists of two parts. The first part introduces basic notions in convex analysis and standard first-order convex optimization algorithms. The second part focuses on solving online optimization and minimax problems. Below is a tentative list of topics.
- Basic convex analysis I: Convexity, strong convexity, Lipschitzness, smoothness, optimality condition, etc.
- Gradient descent.
- Mirror descent.
- Acceleration.
- Proximal methods.
- Smoothing.
- Frank-Wolfe method.
- Basic convex analysis II: Subgradient & subdifferential.
- Mirror descent revisited.
- Online mirror descent.
- Learning in games.
- Follow the regularized leader.
- Optimistic methods. |

課程目標 |
After taking this course, the students are expected to have the ability to:
．Characterize the pros and cons of an optimization algorithm.
．Choose an appropriate optimization algorithm for a given application scenario.
．Do basic complexity analyses of optimization algorithms.
．Read advanced literature in optimization and algorithm design. |
|
課程要求 |
Prerequisites: Multivariate calculus, linear algebra, and probability.
Knowledge in convex analysis, statistics, and/or machine learning are helpful but not necessary. |
