Lifting DecPOMDPs for Nanoscale Systems -- A Work in Progress

no code implementations18 Oct 2021 Tanya Braun, Stefan Fischer, Florian Lau, Ralf Möller

DNA-based nanonetworks have a wide range of promising use cases, especially in the field of medicine.

Exploring Unknown Universes in Probabilistic Relational Models

no code implementations7 Jan 2020 Tanya Braun, Ralf Möller

Large probabilistic models are often shaped by a pool of known individuals (a universe) and relations between them.

Taming Reasoning in Temporal Probabilistic Relational Models

no code implementations16 Nov 2019 Marcel Gehrke, Ralf Möller, Tanya Braun

Evidence often grounds temporal probabilistic relational models over time, which makes reasoning infeasible.

Preventing Unnecessary Groundings in the Lifted Dynamic Junction Tree Algorithm

no code implementations2 Jul 2018 Marcel Gehrke, Tanya Braun, Ralf Möller

The lifted dynamic junction tree algorithm (LDJT) efficiently answers filtering and prediction queries for probabilistic relational temporal models by building and then reusing a first-order cluster representation of a knowledge base for multiple queries and time steps.

Fusing First-order Knowledge Compilation and the Lifted Junction Tree Algorithm

no code implementations2 Jul 2018 Tanya Braun, Ralf Möller

Standard approaches for inference in probabilistic formalisms with first-order constructs include lifted variable elimination (LVE) for single queries as well as first-order knowledge compilation (FOKC) based on weighted model counting.

Answering Hindsight Queries with Lifted Dynamic Junction Trees
