what is scale_train in dropout layer?

[jwyang]

Dear Shaoqing,

I am wondering what is the acutal meanning for scale_train in your dropout layer. I cannot find such parameter in original Caffe project.

Because i encountered an unknown error when runing your caffe_.mexw64, i have to use my own, but it is not compatible to your prototxt file.

What do you think is the best solution to my issue?

Thanks,

Hi jwyang,

scale_train = true is what offical Caffe doing, scale_train = false, is making the scale operation in testing phase instead of training phase. Please read our code, the difference is obvious.

If you have problem in running the downloaded caffe_.mexw64, please compile one with our modifided Caffe.

thanks, shaoqing, i wil read the codes in your modified Caffe, and compile it for usage.
