"Estimate performance of SVM for regression"

noah977

Hi,

I am building some model files using SVM for REGRESSION (nu-SVR)

I can't seem to find a way to see a performance estimate from this task. Either when training the SVM or using the model file.

I tried the "performance" operator, but it gives me errors.

Any ideas?

Go thru the following steps:

1) Read your data
2) Learn the model (check the keep the example set)
3) Apply the model
4) Regression performance operator

Here's a modification of the SupportVectorMachine.xml file that you can find in the samples (under Learners)

Hi,

please note that the solution earmijo gave calculates only the training error. To get a robust and general performance value you should use a cross validation instead.
