ratio change problem #19

Closed Kelvin-hzm closed 4 months ago

Kelvin-hzm commented 4 months ago

Hello, I'm new in medical image segmentation and I wanna change ratio in la.cfg. So I wonder what cps_ratio and con_ratio mean in la.cfg? Or I just need change the ratio into 0.2?

Hi @Kelvin-hzm

cps_ratio denotes the ratio for rectified pseudo-supervision loss in the paper, while con_ratio denotes the ratio for bidirectional voxel contrastive loss in the paper. Please read our paper for further details.

Typically, the ratio for LA and Pancreas-CT task has been determined for best performance. However, you may explore different ratio settings for other tasks.

Thanks! By the way, when I evaluate the train result, not only I saw the ladice and so on, but I saw some result in bg as prefix. What does their mean?

Sorry for bothering you again, I see your paper and I try to figure out how to change the label ratio(as your paper mentioned 2 results in 10% and 20% labeled data)?

Is it RATIO in la.cfg? So I guess I don't need change cps_ratio and con_ratio, right?

This means the dice of background class, as we use softmax rather than sigmoid for activation.

That's right. You may change this argument for different ratio of labeled images.

Thank you again for your patience! I got it.
