We characterize probabilities in Bayesian networks in terms of algebraic expressions called quasi-probabilities. These are arrived at by casting Bayesian networks as noisy AND-OR-...
We present a conceptual framework for validating reusable behavioral models. The setting for this work is a modern product development environment in which design is performed by ...
XML has emerged as the universal standard for exchanging and externalizing data. Software products of all kinds are being upgraded to "support XML." Typically this means...
Nonnegative Matrix Factorization (NMF) is the problem of approximating a nonnegative matrix with the product of two low-rank nonnegative matrices and has been shown to be particul...
