nans in icd labels

[ChantalMP]

Hi,

I noticed in your data for a lot of patients the icd labels are all nan. How did you deal with this when training for the icd prediction task? Did you set the label for these patients to "Unknown"?
It looks like it in the code, but I wonder, because in your paper in Table 7 the majority class accuracy for Unknown is label 0 with 100%.

Thank you and best regards
