sample.conditional function

Conditional sampling method

Generating samples from the distribution

sample.conditional(crf, size, clamped, sample.method, ...)

Arguments

• crf: The CRF
• size: The sample size
• clamped: The vector of fixed values for clamped nodes, 0 for unfixed nodes
• sample.method: The sampling method to solve the clamped CRF
• ...: The parameters for sample.method

Returns

This function will return a matrix with size rows and crf$n.nodes columns, in which each row is a sampled configuration.

Details

Conditional sampling (takes another sampling method as input)

Examples

library(CRF)
data(Small)
s <- sample.conditional(Small$crf, 100, c(0,1,0,0), sample.exact)
