Probabilistic Temporal Reasoning using Superposition Semantics
ACM Transactions on Computational Logic (TOCL), Just Accepted https://doi.org/10.1145/3714427Temporal logics over finite traces have recently seen wide application in a number of areas, from business process modelling, monitoring, and mining to planning and decision making. However, real-life dynamic systems contain a degree of uncertainty which ...

Query2GMM: Learning Representation with Gaussian Mixture Model for Reasoning over Knowledge Graphs
WWW '24: Proceedings of the ACM Web Conference 2024Pages 2149–2158https://doi.org/10.1145/3589334.3645569Logical query answering over Knowledge Graphs (KGs) is a fundamental yet complex task. A promising approach to achieve this is to embed queries and entities jointly into the same embedding space. Research along this line suggests that using multi-modal ...

Aleatoric Predicates: Reasoning about Marbles
AAMAS '24: Proceedings of the 23rd International Conference on Autonomous Agents and Multiagent SystemsPages 2267–2269Aleatoric Logic is the logic of dice, where Boolean propositions are replaced by independent probabilistic events. In a first order extension of this notion, Aleatoric predicates are applied to domain elements selected via independent probabilistic ...

SACBP: Belief space planning for continuous-time dynamical systems via stochastic sequential action control
International Journal of Robotics Research (RBRS), Volume 40, Issue 10-11Pages 1167–1195https://doi.org/10.1177/02783649211037697We propose a novel belief space planning technique for continuous dynamics by viewing the belief system as a hybrid dynamical system with time-driven switching. Our approach is based on the perturbation theory of differential equations and extends ...

Extended Goal Recognition: A Planning-Based Model for Strategic Deception
AAMAS '21: Proceedings of the 20th International Conference on Autonomous Agents and MultiAgent SystemsPages 871–879Goal recognition is the problem of determining an agent's intent by observing its actions. In the context of AI research, the problem is tackled for two quite different purposes: to determine an agent's most probable goal or, for human-aware planning ...

Probabilistic Control Argumentation Frameworks
AAMAS '21: Proceedings of the 20th International Conference on Autonomous Agents and MultiAgent SystemsPages 519–527In this paper we present Probabilistic Control Argumentation Frameworks (PCAFs) that extend classical Control Argumentation Frameworks (CAFs) to take into account probabilistic information in the reasoning process. We show that probabilities can be used ...
