Statistics-Powered ML: Reliable Black-Box Inference from Untrusted Data
Abstract AI systems are increasingly shaping people’s lives, opportunities, and scientific progress. But how can we trust the inferences of such complex, black-box systems? This question becomes even more urgent in the presence of two core challenges that are ubiquitous in high-stakes applications: data scarcity and test-time distribution shift. These issues not only limit… Continue Reading Statistics-Powered ML: Reliable Black-Box Inference from Untrusted Data

The beauty and mystery of total variation
Abstract: The variational distance between probability distributions is, in some natural sense, the canonical one. Its central importance is readily evident in probability, statistics, privacy, and algorithms. Unfortunately, it is an analytically unwieldy object, and in particular, is strongly computationally intractable, even for products of Bernoullis. This talk, after providing the necessary background, will discuss… Continue Reading The beauty and mystery of total variation

Process Mining in Stochastic Settings
Abstract: Alignment-based conformance checking constructs optimal correspondences between observed process executions and normative models, enabling precise identification of deviations for root-cause analysis and process improvement. However, two fundamental challenges limit its applicability in modern settings: exponential state-space growth, which renders exact methods infeasible for very long traces, and uncertainty introduced when activity labels are inferred… Continue Reading Process Mining in Stochastic Settings
