Augmenting Continuous Time Bayesian Networks with Clocks

no code implementations ICML 2020 Nicolai Engelmann, Dominik Linzner, Heinz Koeppl

Structured stochastic processes evolving in continuous time present a widely adopted framework to model phenomena occurring in nature and engineering.

Active Learning of Continuous-time Bayesian Networks through Interventions

no code implementations31 May 2021 Dominik Linzner, Heinz Koeppl

We propose a novel criterion for experimental design based on a variational approximation of the expected information gain.

Continuous-Time Bayesian Networks with Clocks

Structured stochastic processes evolving in continuous time present a widely adopted framework to model phenomena occurring in nature and engineering.

A Variational Perturbative Approach to Planning in Graph-based Markov Decision Processes

no code implementations4 Dec 2019 Dominik Linzner, Heinz Koeppl

We present a novel approximate solution method for multi-agent Markov decision problems on graphs, based on variational perturbation theory.

Scalable Structure Learning of Continuous-Time Bayesian Networks from Incomplete Data

no code implementations NeurIPS 2019 Dominik Linzner, Michael Schmidt, Heinz Koeppl

Instead of sampling and scoring all possible structures individually, we assume the generator of the CTBN to be composed as a mixture of generators stemming from different structures.

Cluster Variational Approximations for Structure Learning of Continuous-Time Bayesian Networks from Incomplete Data

no code implementations NeurIPS 2018 Dominik Linzner, Heinz Koeppl

Existing approximation techniques, such as sampling and low-order variational methods, either scale unfavorably in system size, or are unsatisfactory in terms of accuracy.
