Probabilistic logic with independence
(ELSEVIER SCIENCE INC, 2008)
This paper investigates probabilistic logics endowed with independence relations. We review propositional probabilistic languages without and with independence. We then consider graph-theoretic representations for propositional ...
ALGORITHM FOR PROBABILISTIC ANALYSIS of DISTRIBUTION SYSTEMS WITH DISTRIBUTED GENERATION
(Univ Nac Colombia, Fac Nac Minas, 2011-10-01)
In this paper an efficient algorithm for probabilistic analysis of unbalanced three-phase weakly-meshed distribution systems is presented. This algorithm uses the technique of Two-Point Estimate Method for calculating the ...
A proposal for reliability evaluation of components on electric power distribution system integrating probabilistic models and fuzzy inference systems
The system reliability depends on the reliability of its components itself. Therefore, it is necessary a methodology capable of inferring the state of functionality of these components to establish reliable indices of ...
Complexity of inferences in polytree-shaped semi-qualitative probabilistic networks
Semi-qualitative probabilistic networks (SQPNs) merge two important graphical model formalisms: Bayesian networks and qualitative probabilistic networks. They provade a very Complexity of inferences in polytree-shaped ...
Probabilistic assessment of asphalt pavement design
In Chile, as in many South American countries, AASHTO-93 is the current official method for the design of asphalt pavements. The method gives an estimated number of 80 kN standard axle loads (W18) that the pavement can ...
Assembling a consistent set of sentences in relational probabilistic logic with stochastic independence
(ELSEVIER SCIENCE BV, 2009)
We examine the representation of judgements of stochastic independence in probabilistic logics. We focus on a relational logic where (i) judgements of stochastic independence are encoded by directed acyclic graphs, and ...
Bagging k-dependence probabilistic networks: An alternative powerful fraud detection tool
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
Fraud is a global problem that has required more attention due to an accentuated expansion of modern technology and communication. When statistical techniques are used to detect fraud, whether a fraud detection model is ...
A new probabilistic canopy dynamics model (SLCD) that is suitable for evergreen and deciduous forest ecosystems
(Elsevier B.V., 2014-10-24)
There are strong uncertainties regarding LAI dynamics in forest ecosystems in response to climate change. While empirical growth & yield models (G&YMs) provide good estimations of tree growth at the stand level on a yearly ...
A probabilistic approach for assessing the significance of contextual variables in nonparametric frontier models: an application to brazilian banks.
(Brazilian Review of Econometrics, São Paulo, v. 28, n. 1, p. 11-125, may 2008., 2011)
