Learnability of Complex Objects in Modern AI

Show Abstract

As machine learning and AI systems become increasingly pervasive and are deployed in high-stakes domains, developing theoretical foundations to understand and analyze their behavior has become more challenging, yet more pressing than ever before. Modern AI systems learn sophisticated structures that far exceed the analytical reach of classical learning theory and increasingly operate in environments where learning occurs in the presence of other learners.

In this talk, I will present new directions in learning theory that provide principled guarantees for increasingly complex AI systems. I will discuss general learnability guarantees for rich structured objects based on dual function classes and show how they apply to a broad range of settings, including using machine learning for algorithm design and automating hyperparameter tuning for machine learning itself. Finally, I will highlight emerging challenges for learning in the presence of other learners, spanning both cooperative settings and competitive strategic interactions.

Convex Analysis at Infinity: An Introduction to Astral Space

Show Abstract

Not all convex functions have finite minimizers; some can only be minimized by a sequence as it heads to infinity, making it much harder, for instance, to prove convergence. This work develops an expansive new theory for understanding such minimizers at infinity, introducing astral space, a compact extension of Euclidean space to which such points at infinity have been added. Astral space is constructed to be as small as possible while still ensuring that all linear functions can be continuously extended to the new space. Astral space is especially compatible with standard convex analysis and is meant to provide the foundation for a more complete theory. Although not a vector space, nor even a metric space, astral space is nevertheless so well-structured as to allow useful and meaningful extensions of the most important concepts from convex analysis, including convexity of sets and functions, conjugacy, separation theorems, subdifferentials, as well as central topics from optimization and applications. Applied to widely used algorithms, these tools afford simplified proofs of convergence, even when the only minimizers are at infinity.

This is joint work with Miroslav Dudík and Matus Telgarsky. For further reading, see aka.ms/astral.
