Lifted Causal Inference

Malte Luttermann, Tanya Braun, Ralf Möller +1

Lifted inference exploits indistinguishabilities in probabilistic graphical models by using a representative for indistinguishable objects, thereby speeding up query answering whil…

Inducing Comparability of Factorised Probability Distributions

Jan Speller, Malte Luttermann, Marcel Gehrke +1

To allow for principled comparison between two probabilistic graphical models defined over non-identical variable sets, they have to be lifted to a common measurable space. To this…

On the Detection of Commutative Factors in Factor Graphs: Necessary and Sufficient Conditions

Malte Luttermann, Ralf Möller, Marcel Gehrke

Exploiting the indistinguishability of objects in a probabilistic graphical model such as a factor graph is key to lifted probabilistic inference algorithms and allows for tractabl…

Compression versus Accuracy: A Hierarchy of Lifted Models

Jan Speller, Malte Luttermann, Marcel Gehrke +1

Probabilistic graphical models that encode indistinguishable objects and relations among them use first-order logic constructs to compress a propositional factorised model for more…

Approximate Lifted Model Construction

Malte Luttermann, Jan Speller, Marcel Gehrke +3

Probabilistic relational models such as parametric factor graphs enable efficient (lifted) inference by exploiting the indistinguishability of objects. In lifted inference, a repre…

Lifting Factor Graphs with Some Unknown Factors for New Individuals

Malte Luttermann, Ralf Möller, Marcel Gehrke

Lifting exploits symmetries in probabilistic graphical models by using a representative for indistinguishable objects, allowing to carry out query answering more efficiently while…
