The Target Discounted-Sum Problem
Udi Boker, Thomas A. Henzinger, Jan Otop
The target discounted-sum problem is the following: Given a rational discount factor and three rational values , and , does there exist a finite or an infinite sequ…
Flavors of Quantifiers in Hyperlogics
Marek Chalupa, Thomas A. Henzinger, Ana Oliveira da Costa
Hypertrace logic is a sorted first-order logic with separate sorts for time and execution traces. Its formulas specify hyperproperties, which are properties relating multiple trace…
Monitoring Hyperproperties over Observed and Constructed Traces
Marek Chalupa, Thomas A. Henzinger, Ana Oliveira da Costa
Hyperproperties specify system requirements that relate multiple executions. Reasoning about such properties naturally involves executions that play different roles: some correspon…
Alignment Monitoring
Thomas A. Henzinger, Konstantin Kueffner, Vasu Singh +1
Formal verification provides assurances that a probabilistic system satisfies its specification--conditioned on the system model being aligned with reality. We propose alignment mo…
Algorithmic Fairness: A Runtime Perspective
Filip Cano, Thomas A. Henzinger, Konstantin Kueffner
Fairness in AI is traditionally studied as a static property evaluated once, over a fixed dataset. However, real-world AI systems operate sequentially, with outcomes and environmen…
Formal Verification of Neural Certificates Done Dynamically
Thomas A. Henzinger, Konstantin Kueffner, Emily Yu
Neural certificates have emerged as a powerful tool in cyber-physical systems control, providing witnesses of correctness. These certificates, such as barrier functions, often lear…
