Setting the number of Maximum iterations in MATLAB

Question

Hi, I want to know how I can set the number of Maximum Iterations(want to increase it) in MATLAB. Does anybody knows?

I am using svmtrain

Answer 1

you can pass options using either the 'SMO_OPTS' or the 'QUADPROG_OPTS' flags depending on which method you are using

SVMTRAIN(...,'QUADPROG_OPTS',OPTIONS) 

or

SVMTRAIN(...,'SMO_OPTS',SMO_OPTIONS)

to create QP options, use optimset, to create SMO_OPTS, use svmsmoset. either way, it's the maxiter field that you want to change.

doc svmsmoset

OPTIONS = SVMSMOSET('NAME1',VALUE1,'NAME2',VALUE2,...) 

MaxIter

Maximum number of iterations of main loop. If this number is exceeded before the algorithm converges then the algorithm stops and gives an error. Default value is 15000.

By the way, help svmtrain or doc svmtrain contains all this info
