I trained AlexNet with your design but only got 0.4568 accuracy. Just want to confirm if you got similar result as me.

Hi All,

Thanks for open source your design and providing interface to caffe implementation! I have a question about evaluating your performance in terms of training time of alexnet.

Here is the result of time consumption of traditional caffe over alexnet:

I evaluate time performance with the built-in support of caffe over single GTX1080. But I believe you did speed up since I could tell from the time-stamp of saved models by caffe. May I ask how to correctly evaluate your time performance?

Thanks!
