Subject: difference between Mallet optimization methods in training

Hi all,

I was wondering what is the difference between CRFTrainerByValueGradients
and CRFTrainerByStochasticGradient? I'm using the following 2 codes:

(1)

CRFTrainerByStochasticGradient crfTrainer =
     new CRFTrainerByStochasticGradient(crf, trainingData);


(2)

CRFOptimizableByLabelLikelihood optLabel =

     new CRFOptimizableByLabelLikelihood(crf, trainingData);


Optimizable.ByGradientValue[] opts =

     new Optimizable.ByGradientValue[]{optLabel};



CRFTrainerByValueGradients crfTrainer =
new CRFTrainerByValueGradients(crf, opts);



Thanks,
Amir
