circle-loss-for-reid

we show simple reproduction of circle loss for reid. we let resnet50 as the baseline without any trick.

paper: https://arxiv.org/pdf/2002.10857.pdf

CircleLoss is in losses.py

Run

>>> python train2.py

Implement

• Dataset: market1501
• baseline: resnet50 without fc and tricks

rank-1	mAP	gamma	m	lr	lr-decay	step	batch
82%		56	0.3	0.00035	0.1	30	128

circle loss

the dist of the circle loss achieved by cos dist in paper, we add euclidean dist in the loss.py
