Getting started in probabilistic graphical models. [PDF]

open access: yesPLoS Computational Biology, 2007
Probabilistic graphical models (PGMs) have become a popular tool for computational analysis of biological data in a variety of domains. But, what exactly are they and how do they work?

Mixture-Based Probabilistic Graphical Models for the Label Ranking Problem [PDF]

open access: yesEntropy, 2021
The goal of the Label Ranking (LR) problem is to learn preference models that predict the preferred ranking of class labels for a given unlabeled instance. Different well-known machine learning algorithms have been adapted to deal with the LR problem. In

Generalized Permutohedra from Probabilistic Graphical Models [PDF]

open access: yesSIAM Journal on Discrete Mathematics, 2017
A graphical model encodes conditional independence relations via the Markov properties. For an undirected graph these conditional independence relations can be represented by a simple polytope known as the graph associahedron, which can be constructed as

Robust Depth Image Acquisition Using Modulated Pattern Projection and Probabilistic Graphical Models [PDF]

open access: yesSensors, 2016
Depth image acquisition with structured light approaches in outdoor environments is a challenging problem due to external factors, such as ambient sunlight, which commonly affect the acquisition procedure.

Learning structurally consistent undirected probabilistic graphical models. [PDF]

open access: yesProc Int Conf Mach Learn, 2009
In many real-world domains, undirected graphical models such as Markov random fields provide a more natural representation of the statistical dependency structure than directed graphical models. Unfortunately, structure learning of undirected graphs using likelihood-based scores remains difficult because of the intractability of computing the partition

Probabilistic Graphical Models [PDF]

open access: yes, 2014
This report presents probabilistic graphical models that are based on imprecise probabilities using a simplified language. In particular the discussion is focused on credal networks and discrete domains. It describes the building blocks of credal networks algorithms to perform inference and discusses on complexity results and related work.

Strengthening Probabilistic Graphical Models: The Purge-and-Merge Algorithm

open access: yesIEEE Access, 2021
Probabilistic graphical models (PGMs) are powerful tools for solving systems of complex relationships over a variety of probability distributions. However, while tree-structured PGMs always result in efficient and exact solutions, inference on graph (or ...

The Role of Instrumental Variables in Causal Inference Based on Independence of Cause and Mechanism

open access: yesEntropy, 2021
Causal inference methods based on conditional independence construct Markov equivalent graphs and cannot be applied to bivariate cases. The approaches based on independence of cause and mechanism state, on the contrary, that causal discovery can be ...
