What makes the huge performance boost over official implementations?

Hi, @sunnyxiaohu
Thanks for your excellent and helpful implementation of R-C3D.
I notice that your implementation reports a much higher mAP value on THUMOS14 and wonder what makes the difference.
I guess that you conduct extensive experiments during the implmentation. So according to your experience, what are the main causes?
Thanks!

I have the same question. How did you gain such significant improvement from the original implementation? Is it because you use multiple GPUs to train?

Thank you very much!
