Hi
I want to use the KNN to interpolate the incomplete data matrix (one row represents a sample) which is not normalized. If I normalized the incomplete data matrix before KNN (only consider not NaN values), and then use the KNN to interpolate the values (which is NaN). I do not know whether I still need normalized the complete matrix.

You won't need to normalize it.
