What is "0.78,0.65,8.57" in concat? Thanks

[xmengli]

weight for background, liver, and tumor.

How to calculate it ? Thanks

[xmengli]

Call the dataloader for many iterations, then check the voxel number of the background, liver and tumor respectively.

Thank you very much!

Why weight of tumor great than liver and background ?

[xmengli]

When you call dataloader for many iterations, you can find the voxel amount of tumor is small.

How to calculate weight ? Tumor/sum(background,liver,tumor) ?

[xmengli]

Yes, the weight is calculated by Tumor/sum(background,liver,tumor) during the training stages.
