Content

This course teaches an overview of modern optimization methods, for applications in machine learning and data science. In particular, scalability of algorithms to large datasets will be discussed in theory and in implementation.

Basic Contents:

Convexity, Gradient Methods, Proximal algorithms, Stochastic and Online Variants of mentioned methods, Coordinate Descent Methods, Subgradient Methods, Frank-Wolfe, Accelerated Methods, Primal-Dual context and certificates, Lagrange and Fenchel Duality, Second-Order Methods, Quasi-Newton Methods. Gradient-Free and Zero-Order Optimization.

Advanced Contents:

Parallel and Distributed Optimization Algorithms, Synchronous and Asynchronous Communication.

Lower Bounds.

Non-Convex Optimization: Convergence to Critical Points, Saddle-Point methods, Alternating minimization for matrix and tensor factorizations


An optional, graded, mini-project allows to explore the real-world performance aspects of the algorithms and variants of the course.
