Harnessing Incremental Answer Set Solving for Reasoning in Assumption-Based Argumentation

1 code implementation9 Aug 2021 Tuomo Lehtonen, Johannes P. Wallner, Matti Järvisalo

In this work, we harness recent advances in incremental ASP solving for developing effective algorithms for reasoning tasks in the logic programming fragment of ABA that are presumably hard for the second level of the polynomial hierarchy, including skeptical reasoning under preferred semantics as well as preferential reasoning.

Learning Chordal Markov Networks via Branch and Bound

no code implementations NeurIPS 2017 Kari Rantanen, Antti Hyttinen, Matti Järvisalo

We present a new algorithmic approach for the task of finding a chordal Markov network structure that maximizes a given scoring function.

no code implementations13 May 2016 James Cussens, Matti Järvisalo, Janne H. Korhonen, Mark Bartlett

The challenging task of learning structures of probabilistic graphical models is an important problem within modern AI research.

Causal Discovery from Subsampled Time Series Data by Constraint Optimization

no code implementations25 Feb 2016 Antti Hyttinen, Sergey Plis, Matti Järvisalo, Frederick Eberhardt, David Danks

This paper focuses on causal structure estimation from time series data in which measurements are obtained at a coarser timescale than the causal timescale of the underlying system.
