AutoPlanBench: Automatically generating benchmarks for LLM planners from PDDL

1 code implementation16 Nov 2023 Katharina Stein, Daniel Fišer, Jörg Hoffmann, Alexander Koller

LLMs are being increasingly used for planning-style tasks, but their capabilities for planning and reasoning are poorly understood.

Specifying and Testing $k$-Safety Properties for Machine-Learning Models

1 code implementation13 Jun 2022 Maria Christakis, Hasan Ferit Eniser, Jörg Hoffmann, Adish Singla, Valentin Wüstholz

Here, we show the wide applicability of $k$-safety properties for machine-learning models and present the first specification language for expressing them.

An Explainable AI System for the Diagnosis of High Dimensional Biomedical Data

no code implementations5 Jul 2021 Alfred Ultsch, Jörg Hoffmann, Maximilian Röhnert, Malte Von Bonin, Uta Oelschlägel, Cornelia Brendel, Michael C. Thrun

A comparison to a selection of state of the art explainable AI systems shows that ALPODS operates efficiently on known benchmark data and also on everyday routine case data.

Iterative Planning with Plan-Space Explanations: A Tool and User Study

no code implementations19 Nov 2020 Rebecca Eifler, Jörg Hoffmann

Adopting the recent approach to answer such questions in terms of plan-property dependencies, here we implement a tool and user interface for human-guided iterative planning including plan-space explanations.

Generating Instructions at Different Levels of Abstraction

no code implementations COLING 2020 Arne Köhn, Julia Wichlacz, Álvaro Torralba, Daniel Höller, Jörg Hoffmann, Alexander Koller

When generating technical instructions, it is often convenient to describe complex objects in the world at different levels of abstraction.

Tracking the Race Between Deep Reinforcement Learning and Imitation Learning -- Extended Version

no code implementations3 Aug 2020 Timo P. Gros, Daniel Höller, Jörg Hoffmann, Verena Wolf

Our evaluations show that for this sequential decision making problem, deep reinforcement learning performs best in many aspects even though for imitation learning optimal decisions are considered.

Towards Automated Network Mitigation Analysis (extended)

no code implementations15 May 2017 Patrick Speicher, Marcel Steinmetz, Jörg Hoffmann, Michael Backes, Robert Künnemann

Penetration testing is a well-established practical concept for the identification of potentially exploitable security weaknesses and an important component of a security audit.

Message-Based Web Service Composition, Integrity Constraints, and Planning under Uncertainty: A New Connection

no code implementations15 Jan 2014 Jörg Hoffmann, Piergiorgio Bertoli, Malte Helmert, Marco Pistore

The special case, which we term "forward effects", is characterized by the fact that every ramification of a web service application involves at least one new constant generated as output by the web service.
