Shai Ben-David
Prof Ben-David research interests span a range of topics in computer science theory.
He has been working on a wide range to topic including logic, theory of distributed computation and computational complexity. In recent years his focus turned to machine learning theory. Among his notable contribution in that field are pioneering steps in the analysis of domain adaptation, of learnability of real valued functions, and of change detection in streaming data. In the domain of unsupervised learning Shai has made fundamental contributions to the theory of clustering (developing tools for guiding users in picking algorithms to match their domain needs) and distribution learning. He has also published seminal works on average case complexity, competitive analysis and alternatives to worst-case complexity.
Prof Ben-David’s papers have won various awards, most recently, Best Paper awards in NeurIPS 2018 and in ALT 2023.

Shai earned his PhD in mathematics from the Hebrew University in Jerusalem and has been a professor of computer science at the Technion (Israel Institute of Technology).  Over the years, he has held visiting faculty positions at the Australian National University, Cornell University, ETH Zurich, TTI Chicago and the Simons institute at Berkeley.
Since 2004 Shai is a professor at the David Cheriton school of computer science at U Waterloo, and since 2019 a faculty member at the Vector Institute, Toronto. He is also a Canada CIFAR AI chair, a University research chair at U waterloo and a Fellow of the ACM. 

Highlights:
President of the Association for Computational Learning Theory (2009-2012).
Program chair for the major machine learning theory conferences (COLT and ALT, and area chair for ICML, NIPS and AISTATS). 
Co-authored the textbook "Understanding machine learning: from theory to algorithms".

Courses

Shai Ben-David
I will devote three of my lectures to an introduction to the theory of machine learning and the fundamental statistical learning generalization results. My remaining lectures will cover three concrete and more advanced topics: Clustering, unsupervised learning of probability distributions and fairness for machine-learning-based decision making.
 
Amin Karbasi
Combinatorial optimization: Many scientific and engineering models feature inherently discrete decision variables—from phrases in a corpus to objects in an image. The study of how to make near-optimal decisions from a massive pool of possibilities is at the heart of combinatorial optimization. Many of these problems are notoriously hard, and even those that are theoretically tractable may not scale to large instances. However, the problems of practical interest are often much more well-behaved and possess extra structures that allow them to be amenable to exact or approximate optimization techniques. Just as convexity has been a celebrated and well-studied condition under which continuous optimization is tractable, submodularity is a condition for which discrete objectives may be optimized.
 
Continuous optimization: Continuous methods have played a celebrated role in submodular optimization, often providing the tightest approximation guarantees. We discuss how first order methods can help us solve combinatorial problems in modern machine learning applications.
 

Jessica Sorrell
Replicability of outcomes in scientific research is a necessary condition to ensure that the conclusions of the studies reflect inherent properties of the underlying population and are not an artifact of the methods that scientists used or the random sample of the population that the study was conducted on. In its simplest form, it requires that if two different groups of researchers carry out an experiment using the same methodologies but different samples of the same population, it better be the case that the two outcomes of their studies are statistically indistinguishable. We discuss this notion in the context of machine learning and try to understand for which learning problems statistically indistinguishable learning algorithms exist. 

Amir Yehudayoff
Learning entails succinct representation of data. Learning algorithms perform some sort of compression of information. A seminal definition capturing this phenomenon is that of sample compression schemes. The mini-course shall introduce sample compression schemes and survey deep connections to other notions of learning and areas of mathematics.

Nikita Zhitovoskiy
The Exponential Weights (EW) algorithm is a versatile tool with broad utility across statistics and machine learning. Originally developed in information theory, EW has an elegant theoretical framework that tackles many problems. First, we will see how EW can estimate discrete distributions. Next, we will examine its role in ensemble methods for aggregating multiple estimators. Finally, we will discuss EW in logistic and linear regression, where it enables regularization through an online learning approach.
