decode.block {CRF}

R Documentation

Decoding method using block iterated conditional modes algorithm

Description

Computing the most likely configuration for CRF

Usage

decode.block(
  crf,
  blocks,
  decode.method = decode.tree,
  restart = 0,
  start = apply(crf$node.pot, 1, which.max),
  ...
)

Arguments

crf	The CRF
blocks	A list of vectors, each vector containing the nodes in a block
decode.method	The decoding method to solve the clamped CRF
restart	Non-negative integer to control how many restart iterations are repeated
start	An initial configuration, a good start will significantly reduce the seraching time
...	The parameters for decode.method

Details

Approximate decoding with the block iterated conditional modes algorithm

Value

This function will return the most likely configuration, which is a vector of length crf$n.nodes.

Examples

library(CRF)
data(Small)
d <- decode.block(Small$crf, list(c(1,3), c(2,4)))
