demo.m code problem #2

Open guoyuanxiong opened 6 years ago

guoyuanxiong commented 6 years ago

Thanks for developing such a library. When trying to use it, I found that when I change the values of "d" and "n" in the file "demo.m", there will be some errors in the convergence results. For instance, if I choose "d = 105", "n = 30000", the returned results are very strange as shown before:

SVRG: Epoch = 000, cost = Inf, optgap = Inf SVRG: Epoch = 001, cost = NaN, optgap = NaN

Is there any problem with the code for the reusability?

Thanks!

I have checked the code and found that some values indicated "-Inf" or "NaN" in logistic_regression.m in some cases.

I fixed temporally the codes, and uploaded it to the system. Please make them checked.

If you have further problems, please let me known.

Regards,

Hiro

Seems to work correctly now at my side. Thanks.
