nbcEval
Evaluation for the NBC (naive bayes classifier)
Contents
Syntax
- [computedClass, logLike, recogRate, hitIndex]=nbcEval(DS, cPrm, showPlot)
- If DS does not have "output" field, then this command won't return "recogRate" and "hitIndex".
Description
[computedClass, logLike, recogRate, hitIndex]=nbcEval(DS, cPrm, showPlot) returns the evaluation results of NBC
Example
DS=prData('iris'); DS.input=DS.input(3:4, :); trainSet.input=DS.input(:, 1:2:end); trainSet.output=DS.output(:, 1:2:end); testSet.input=DS.input(:, 2:2:end); testSet.output=DS.output(:, 2:2:end); [cPrm, logLike1, recogRate1]=nbcTrain(trainSet); [computedClass, logLike2, recogRate2, hitIndex]=nbcEval(testSet, cPrm, 1); fprintf('Inside recog rate = %g%%\n', recogRate1*100); fprintf('Outside recog rate = %g%%\n', recogRate2*100);
Inside recog rate = 97.3333% Outside recog rate = 96%
