A survey of the theory of coherent lower previsions

E Miranda - International Journal of Approximate Reasoning, 2008 - Elsevier
This paper presents a summary of Peter Walley's theory of coherent lower previsions. We
introduce three representations of coherent assessments: coherent lower and upper …

probability values. The paper first reviews basic concepts and presents a brief historical …

Imprecise probability trees: Bridging two theories of imprecise probability

G De Cooman, F Hermans - Artificial Intelligence, 2008 - Elsevier

[HTML][HTML] Robust classification of multivariate time series by imprecise hidden Markov models

A Antonucci, R De Rosa, A Giusti, F Cuzzolin - International Journal of …, 2015 - Elsevier
A novel technique to classify time series with imprecise hidden Markov models is presented.
The learning of these models is achieved by coupling the EM algorithm with the imprecise …

Bayesian networks with imprecise probabilities: Theory and application to classification

Bayesian networks are powerful probabilistic graphical models for modelling uncertainty.
Among others, classification represents an important application: some of the most used …

Epistemic irrelevance in credal nets: the case of imprecise Markov trees

G De Cooman, F Hermans, A Antonucci… - International Journal of …, 2010 - Elsevier
We focus on credal nets, which are graphical models that generalise Bayesian nets to
imprecise probability. We replace the notion of strong independence commonly used in …

Statistical matching of multiple sources: A look through coherence

B Vantaggi - International Journal of Approximate Reasoning, 2008 - Elsevier
In several applications there is the need to consider different data sources and to integrate
information: a specific case is the so-called statistical matching, where data sources have …

[PDF][PDF] Interval-valued regression and classification models in the framework of machine learning

LV Utkin, FPA Coolen - ISIPTA, 2011 - Citeseer

Partial identification with missing data: concepts and findings

CF Manski - International Journal of Approximate Reasoning, 2005 - Elsevier
The traditional way to cope with missing data problems has been to combine the available
