"Algorithm in Cross Validation keep on processing"
Hi,
I am trying to do cross-validation 5 fold, but the SVM and Logistic regression operators in CV keep on processing as shown in the figure below. Its been 10 hours and they are same. The dataset size is 316974 samples with 40 attributes. XML below. Is this due to dataset size? Generally, it needs to show some percentage of completion but it keeps on processing without change.
Thanks,
Varun

@mschmitz yes. That is what I was thinking, I killed with Task Manager.
I'd try a 10% sample first and see if you get a reasonable model at all with these algorithms. I cannot say enough how useful it is to take a 1% to 10% sample as a starting point if you are dealing with large datasets. It saves a lot of headaches later!
Thanks @Telcontar120 I did try it in with few samples and SVM doesn't look good.
Altair Employee@varunm1 ,
keep in mind that you need to tune C of an SVM very carefully (+ kernel parameters).

Altair EmployeeHi @varunm1 ,
300k is simply a lot for an SVM. SVMs scale well in #attributes, but not so well in #samples.
Sadly there is one librarly which does not offer a kill-switch. If i remember correctly RM cannot kill it from the outside and you would need to kill the java process.
