The Semantics of Intermediate CPTs in Variable Elimination
نویسندگان
چکیده
Variable elimination (VE), a central component of Bayesian network inference, starts and ends with clear structure and semantics, yet all intermediate distributions, whether normalized or unnormalized, are denoted as potentials. In this paper, a condition is given stating when intermediate distributions are defined with respect to the joint distribution. Theoretical and practical advantages of these new semantics are given.

On Variable Elimination in Discrete Bayesian Network Inference
We are interested in proving that variable elimination (VE) in discrete Bayesian networks always yields a clearly structured conditional probability table (CPT) rather than a potential as universally stated. A Bayesian network consists of a directed acyclic graph and a corresponding set of CPTs. Based on the conditional independencies holding in the directed acyclic graph, the product of the CP...
متن کاملThe CPT Structure of Variable Elimination in Discrete Bayesian Networks
We show that a conditional probability table (CPT) is obtained after every multiplication and every marginalization step when eliminating variables from a discrete Bayesian network. The main advantage of our work is an improvement in presentation. The probability distributions constructed during variable elimination in Bayesian networks have always been denoted as potentials. Since CPTs are a s...
متن کاملValue Elimination: Bayesian Inference via Backtracking Search
We present Value Elimination, a new algorithm for Bayesian Inference. Given the same variable order ing information, Value Elimination can achieve per formance that is within a constant factor of variable elimination or recursive conditioning, and on some problems it can perform exponentially better, irrespec tive of the variable ordering used by these algorithms. Value Elimination's other f...

متن کاملA Linguistic Analysis of Conference Titles in Applied Linguistics
Over the past twenty-five years, researchers have expressed considerable interest in titles of academic publications. Unfortunately, conference paper titles (CPTs) have only recently begun to receive attention. The aim of this study, therefore, is to investigate the text length, syntactic structure, and lexicon of CPTs in Applied Linguistics. A data set of 698 titles was selected from the 2008 ...
