So that 's th that 's the hard thing. I mean , I understand that there 's this other constraint that you 're considering , is that you wanna have categories that , uh  that would be straightforward for , say , a human being to mark if you had manual annotation. And it 's something that you really think you can pick up. But I think it 's also essential that you wanna look at what are the  confusions that you 're making and how can you come up with , uh , categories that , uh , can clarify these confusions.
Mm - hmm. Hmm.
So , I mean , the standard sort of way of doing that is take a look at the algorithms you 're looking at , but then throw in some discriminative aspect to it.  Y y this is more like , you know , how does LDA differ from PCA ? I mean , they 're the same sort of thing. They 're both orthogonalizing.
Right.
