Decidable Reasoning About Time in Finite-Domain Situation Calculus Theories

no code implementations5 Feb 2024 Till Hofmann, Stefan Schupp, Gerhard Lakemeyer

The most commonly used approach represents time by adding a real-valued fluent $\mathit{time}(a)$ that attaches a time point to each action and consequently to each situation.

Extracting Rules from Event Data for Study Planning

1 code implementation4 Oct 2023 Majid Rafiei, Duygu Bayrak, Mahsa Pourbafrani, Gyunam Park, Hayyan Helal, Gerhard Lakemeyer, Wil M. P. van der Aalst

In this study, we examine how event data from campus management systems can be used to analyze the study paths of higher education students.

Multi-Valued Partial Order Plans in Numeric Planning

no code implementations27 Jul 2023 Hayyan Helal, Gerhard Lakemeyer

Many planning formalisms allow for mixing numeric with Boolean effects.

A Combined Approach of Process Mining and Rule-based AI for Study Planning and Monitoring in Higher Education

no code implementations22 Nov 2022 Miriam Wagner, Hayyan Helal, Rene Roepke, Sven Judel, Jens Doveren, Sergej Goerzen, Pouya Soudmand, Gerhard Lakemeyer, Ulrik Schroeder, Wil van der Aalst

This paper presents an approach of using methods of process mining and rule-based artificial intelligence to analyze and understand study paths of students based on campus management system data and study program models.

Predictive Object-Centric Process Monitoring

no code implementations20 Jul 2022 Timo Rohrer, Anahita Farhang Ghahfarokhi, Mohamed Behery, Gerhard Lakemeyer, Wil M. P. van der Aalst

Objects in OCEL can have attributes that are useful in predicting the next event and timestamp, such as a priority class attribute for an object type package indicating slower or faster processing.

Towards Using Promises for Multi-Agent Cooperation in Goal Reasoning

no code implementations20 Jun 2022 Daniel Swoboda, Till Hofmann, Tarik Viehmann, Gerhard Lakemeyer

One technique to tackle this problem is goal reasoning, where the agent not only reasons about its actions, but also about which goals to pursue.

On the Verification of Belief Programs

no code implementations26 Apr 2022 Daxin Liu, Gerhard Lakemeyer

In this paper, we propose a formalism for belief programs based on a modal logic of actions and beliefs.

Controller Synthesis for Golog Programs over Finite Domains with Metric Temporal Constraints

no code implementations19 Feb 2021 Till Hofmann, Gerhard Lakemeyer

We show that for programs over finite domains and with fully known initial state, the problem of synthesizing a controller that satisfies the constraints while preserving the effects of the original program can be reduced to MTL synthesis.

KM-BART: Knowledge Enhanced Multimodal BART for Visual Commonsense Generation

1 code implementation ACL 2021 Yiran Xing, Zai Shi, Zhao Meng, Gerhard Lakemeyer, Yunpu Ma, Roger Wattenhofer

We present Knowledge Enhanced Multimodal BART (KM-BART), which is a Transformer-based sequence-to-sequence model capable of reasoning about commonsense knowledge from multimodal inputs of images and texts.
