weighted loss

[SonwYang]

Hello, I am interested in loss function combined with size and distance but I have no idea how it works. Can you give me more information（related paper, reference and so on） about it? Thank you.

Hi @yangpeng1995 In the original UNet paper: https://arxiv.org/pdf/1505.04597.pdf the authors introduce the weighted loss that we use here. It describes the "distance" part. Weights related to building size is our idea, but it works in the same way. Cheers.
