Variational message passing (VMP) is an approximate inference technique for continuous- or discrete-valued Bayesian networks, with conjugate-exponential parents, developed by John Winn. VMP was developed as a means of generalizing the approximate variational methods used by such techniques as Latent Dirichlet allocation and works by updating an approximate distribution at each node through messages in the node's Markov blanket.

Famous quotes containing the words message and/or passing:
“No it is better not. She would only ask me to take a message to Albert.”
—Benjamin Disraeli (1804–1881)
“He had the oaks for heating and for light.
He had a hen, he had a pig in sight.
He had a well, he had the rain to catch.
He had a ten-by-twenty garden patch.
Nor did he lack for common entertainment.
That I assume was what our passing train meant.”
—Robert Frost (1874–1963)
