Inference with Seperately Specified Sets of Probabilities in Credal Networks
Jose Carlos Ferreira da Rocha, Fabio Gagliardi Cozman
We present new algorithms for inference in credal networks --- directed acyclic graphs associated with sets of probabilities. Credal networks are here interpreted as encoding stron…
Inference in Polytrees with Sets of Probabilities
Jose Carlos Ferreira da Rocha, Fabio Gagliardi Cozman, Cassio Polpo de Campos
Inferences in directed acyclic graphs associated with probability sets and probability intervals are NP-hard, even for polytrees. In this paper we focus on such inferences, and pro…
Propositional and Relational Bayesian Networks Associated with Imprecise and Qualitative Probabilistic Assesments
Fabio Gagliardi Cozman, Cassio Polpo de Campos, Jaime Ide +1
This paper investigates a representation language with flexibility inspired by probabilistic logic and compactness inspired by relational Bayesian networks. The goal is to handle p…
Belief Updating and Learning in Semi-Qualitative Probabilistic Networks
Cassio Polpo de Campos, Fabio Gagliardi Cozman
This paper explores semi-qualitative probabilistic networks (SQPNs) that combine numeric and qualitative information. We first show that exact inferences with SQPNs are NPPP-Comple…
Complexity Analysis and Variational Inference for Interpretation-based Probabilistic Description Logic
Fabio Gagliardi Cozman, Rodrigo Bellizia Polastro
This paper presents complexity analysis and variational methods for inference in probabilistic description logics featuring Boolean operators, quantification, qualified number rest…
