All Implemented Interfaces:

junit.framework.Test

public class ValidPathsTest
extends AbstractTestCase

Tests that CRF is working with valid probabilities - the sum of all possible labelings is 1. Test that the code to walk through only the valid paths works correctly. Uses a two state model that disallows transitions to self. 010101... or 101010... are the only allowed paths.

Constructor Summary

ValidPathsTest()

Method Summary

void	testRejectInvalidTrainingPath()
void	testSumPaths() Tests that the sum of the likelihoods of the valid paths is 1
void	testSumPathsAllPaths() Tests all 2-state combinations with a restricted model and onlyValidTransitions = false
void	testSumPathsAllPathsCached() Tests all 2-state combinations with a restricted model and onlyValidTransitions = false
void	testSumPathsMoreComplicated() Tests that the sum of the likelihoods of the valid paths is 1, uses a model that allows 0-0
