Rao-Blackwellising Bayesian Causal Inference

no code implementations22 Feb 2024 Christian Toth, Christian Knoll, Franz Pernkopf, Robert Peharz

Specifically, we decompose the problem of inferring the causal structure into (i) inferring a topological order over variables and (ii) inferring the parent sets for each variable.

Understanding the Behavior of Belief Propagation

no code implementations5 Sep 2022 Christian Knoll

Probabilistic graphical models are a powerful concept for modeling high-dimensional distributions.

Active Bayesian Causal Inference

1 code implementation4 Jun 2022 Christian Toth, Lars Lorch, Christian Knoll, Andreas Krause, Franz Pernkopf, Robert Peharz, Julius von Kügelgen

In this work, we propose Active Bayesian Causal Inference (ABCI), a fully-Bayesian active learning framework for integrated causal discovery and reasoning, which jointly infers a posterior over causal models and queries of interest.

Distribution Mismatch Correction for Improved Robustness in Deep Neural Networks

no code implementations5 Oct 2021 Alexander Fuchs, Christian Knoll, Franz Pernkopf

The most common normalization method, batch normalization, reduces the distribution shift during training but is agnostic to changes in the input distribution during test time.

Self-Guided Belief Propagation -- A Homotopy Continuation Method

no code implementations4 Dec 2018 Christian Knoll, Adrian Weller, Franz Pernkopf

Belief propagation (BP) is a popular method for performing probabilistic inference on graphical models.

Fixed Points of Belief Propagation -- An Analysis via Polynomial Homotopy Continuation

no code implementations20 May 2016 Christian Knoll, Franz Pernkopf, Dhagash Mehta, Tianran Chen

Moreover, we show that this fixed point gives a good approximation, and the NPHC method is able to obtain this fixed point.
