Could you post a link to the repo of the Caffe and Matconvnet implementation of these models?
We’ve had this discussion in the past, but I can’t find the thread.
The conclusion was, as far as I remember, that the Caffe model was trained differently, i.e. an advanced model instead of the original architecture. But as I said, I try to find the thread where I compared the implementations. So take this statement with a grain of salt.
