Hi, sum of the product of predicted and ground truth masks is actually the (differentiable part of) mIoU loss.
The code definition definition is here.
Looks like we missed a negative sign in the paper, will fix
from 4k4d.
We originally experimented with L2(MSE) loss for mask loss and it didn't work as well as mIoU
from 4k4d.
Thank you, this is exactly what I was puzzled about. The maskLoss formula in the paper indeed lacks a negative sign.
