lgyhero commented 8 years ago

image I am using Matconvnet to do a binary-classfication job, the train error is decreasing smoothly, but the validation error is jittering....Can anyone explain this? Thanks a lot.

Seems perfectly normal. Probably your validation set is much smaller than the training set, so there is a bit of statistical fluctuation.

Got it. I'v divided the dataset(about 200,000 images) into 80% training set and 20% validation set. Maybe I can offer more images for validation. Thanks very much !@vedaldi I'll close the issue.
