Hi @yasuobinggan ,
Can I provide a pseudo-label for data preprocessing based on rough segmentation of unsupervised data based on baseline model in each fold?
Sorry, I do not understand this.
Could you restatement your question?
Sorry, my English is a little poor. I mean in the semi-supervised segmentation, I also want to pre-crop the unsupervised data according to the rough segmentation, which is the label inferred from the baseline method on the unsupervised data. 半监督设置中,我想在数据预处理阶段对无监督数据也进行基于标签的预crop (根据标签把roi的大致区域切下来), 我想用baseline的nnUNet来提供这个标签。这样处理中一是对无监督数据进行切分预处理,是否违反无监督设置;二是最后还是会在无监督数据上测试衡量效果(transdudtive设置),不清楚以上两点是否违规。
Hi @yasuobinggan ,
我们的benchmark没有设置benchmark的task,所以不存在违规/不违规的问题。 实验中只需要保证你的对比公平即可,比如你自己设计的半监督方法用了crop,那么baseline的方法也应该建立在 crop基础上。
好的,非常感谢您的回复!也感谢你们提供的benchmark!
Hi JunMa, crop preprocessing based on labels is very common in medical image segmentation task. In Task 1, I want to continue to improve the effect through semi-supervised learning, but the unsupervised data requires crop preprocessing. Can I provide a pseudo-label for data preprocessing based on rough segmentation of unsupervised data based on baseline model in each fold? I wonder that if this process will be considered to be cheating? Thank you very much!
