So you  you have the distributions from the training set ,
and then , uh  So this is just a  a histogram of  of  the amplitudes , I guess. Right ? And then   Um , people do this in image processing some.
Mm - hmm.
You have this kind of   of histogram of  of levels of brightness or whatever. And  and  and then ,  when you get a new  new thing that you  you want to adjust to be  better in some way ,  you adjust it so that the histogram of the new data looks like the old data.
