question about action detection performance on activity-net #27

shiyi001 commented 5 years ago

Hello, Tianwei~ I tried to reimplement your action detection experiments on activity-net, but only get a poor result. Here is my results using different iou thresh on NMS:

IOU thresh	map@0.5	map@0.75	map@0.95	average
0.3	0.450	0.274	0.078	0.281
0.4	0.455	0.280	0.078	0.287
0.5	0.450	0.288	0.078	0.292
0.6	0.437	0.298	0.079	0.293
0.7	0.422	0.304	0.080	0.291

I found average number of proposals is far smaller than 100. Does it matter?

I have checked my code several times, but can not find any mistake. Can you help me? Or share your code which generates the detection result. Many thanks.

Hi @shiyi001 , please refer results on our updated paper (my homepage and arxiv), where BSN reach 30.03 average mAP. Thus your results seens close. Please leave your email and I will sent your code.
