Jun 9, 2016 at 10:10 comment added Ronald Monson I agree the improved performance is due to some validation but whether or not it is due to the validation specified in the option or else due to the inbuilt cross-validation still seems questionable to me - see, for example, these runs.
Feb 17, 2016 at 8:39 comment added Sjoerd C. de Vries @ronald You often see that a trained classifier has a lower performance on an out-of-sample test. This is often due to overfitting. In this case performance of the out-of-sample fraction is equal to the training sample, which is quite good and which I feel is due to the presence of the validation sample.
