Once every week while school is in session, EECS invites a distinguished researcher or practitioner in a computer science or electrical and computer engineering-related field to present their ideas and/or work. Talks are generally targeted to electrical engineering and computer science graduate students. This colloquium series is free and open to everyone.

What should be in an XAI explanation? What IFT reveals by studying RTS

Abstract

"What should be in an explanation and what should they look like?” This is a fundamental question to answer in order for Explainable Artificial Intelligience (XAI) to gain the trust of human assessors. To this end, we conducted a pair of studies investigating generation, content, and form of explanations in the Real-Time Strategy (RTS) domain, specifically StarCraft II. First, we observed expert explainers' (shoutcasters) foraging patterns and speech, as they provide explanations in real-time. Second, we used a lab study to examine how participants investigated agent behavior in the same domain - but without the real-time constraint. By conducting this pair of studies, we are able to study both (1) explanations supplied by experts and (2) explanations demanded by assessors. Throughout our studies, we adopted an Information Foraging Theory (IFT) perspective, which allows us to generalize our results. In this talk, we present what these results tell us about how to explain AI systems.

Enabling Complete and Efficient Attack Provenance at Scale

Abstract

In a provenance-aware system, mechanisms gather and report metadata that
describes the history of each data object being processed, allowing users
to understand how objects came to exist in their present state.
Excitingly, we can also use provenance to trace the actions of system
intruders, enabling smarter and faster incident response. In this talk, I
will detail our efforts to achieve trustworthy data provenance in
malicious distributed environments. These efforts have led to the design
and implementation of a provenance-aware operating systems anchored in
trusted hardware, a mechanism that leverages the confinement properties
provided by Mandatory Access Controls to perform efficient policy-based
provenance collection, and most recently an efficient distributed
provenance management framework. Using these architectures, I will
demonstrate that provenance is an invaluable tool for combating critical
security threats including data exfiltration, SQL injection, and even
binary exploitation. By addressing key security and performance
challenges, this work is paving the way for the further proliferation of
provenance capabilities.
