`neg_iou_thresh_lo` value in `ProposalTargetCreator` #932

Open t2kasa opened 5 years ago

Hi,

I want to know that the value 0.0 of neg_iou_thresh_lo is intended or not. In the Fast R-CNN paper, it seems that the assignment for negative samples is decided when between the sample and GT IoU is ranged in [0.1, 0.5). (in section Mini-batch sampling).
