Question about usage of CrossValidation

[function2-llx]

Hello MONAI team,

Recently I'm trying to use CrossValidation class. But after browsing the doc and the source code I get confused about its usage. I don't understand the reason it requires a _split_datalist API for dataset_cls, since I can't find where it's invoked and it is also overridden by the derived class _NsplitsDataset nested in the implementation of get_dataset. Could you please suggest some hints on this or add a more detailed example in the doc?

Thanks in advance!

Hello @Nic-Ma ,

Thanks for the reply! Now I get the intended usage of this class, though I just feel like there should be a more natural and clear way to do this. Maybe I will be back later when I have some more time to discuss and help to improve.
