matlab - Increasing the number of iterations with multisvm -


i'm attempting use multisvm function in matlab. on small data set, works great. increase size need it, , following error:

error using seqminopt>seqminoptimpl (line 198) no convergence achieved within maximum number of iterations.

error in seqminopt (line 81) [alphas offset] = seqminoptimpl(data, targetlabels, ...

error in svmtrain (line 499) [alpha, bias] = seqminopt(training, groupindex, ...

error in multisvm (line 20) models(k) = svmtrain(trainingset,g1vall);

i've been trying solution online , found this: http://www.mathworks.com/matlabcentral/answers/66183,

where advice "so increase maximum number of iterations". problem is, doesn't seem easy do. of novice, trying figure out on own looking through these files, without success. know how can increase number of iterations , solve problem?

svmtrain trying find correct line between e.g. 2 groups. if doesn't find correct line, change parameters in function of line find correct line separated groups , make iteration of iteration parameter. default trying find correct line 15000 times. if use following code, svmtrain try 100000 times find corrected line. time of training naturally longer.

options.maxiter = 100000; my_svm_struct = svmtrain((training, group, 'options', options);

java - Multi-Label Document Classification -

i have database in store data based upon following 3 fields: id, text, {labels}. note each text has been assigned more 1 label \ tag \ class. want build model (weka \ rapidminer \ mahout) able recommend \ classify bunch of labels \ tags \ classes given text. i have heard svm , naive bayes classifier, not sure whether support multi-label classification or not. guides me right direction more welcome! the basic multilabel classification method one-vs.-the-rest (ovr), called binary relevance (br). basic idea take off-the-shelf binary classifier, such naive bayes or svm, create k instances of solve k independent classification problems. in python-like pseudocode: for each class k: learner = svm(settings) # example labels = [class_of(x) == k x in samples] learner.learn(samples, labels) then @ prediction time, run each of binary classifiers on sample , collect labels predict positive. (both training , prediction can done in parallel, since problems assumed ...
