> [@rodrigo.constanzo](#): > > just scale one space (incoming descriptors) to the other (corpus descriptors) this is the classic option then, where scaling doesn’t change much - you take the universe of one and hope the other one will have stuff in that zone. I tried to explain that clearly here: > [@Musaiking non-overlaping spectral descriptor spaces - an attempt at explaining the issue clearly](https://discourse.flucoma.org/t/musaiking-non-overlaping-spectral-descriptor-spaces-an-attempt-at-explaining-the-issue-clearly/1791): > > Hello As you have read for many years, for all the projects and a decade before, I’m obsessed about playing a corpus with the bass. I am sorry if I [repeat myself](https://discourse.flucoma.org/t/mapping-problem-a-potential-solution-a-journal/) I now understand how impossible a generalized solution is, so I am embracing the quirks slight_smile So here goes an explanation. it is a draft of something that should maybe published on non-overlapping spaces on learn. Previously, we spoke about that problem in various ways… here goes 2 basic examples in 2 d to show the problem. … In other words: in your corpus has stuff between -100 and 100 and you scale it 0-1, then you enter a target that wiggles between -200 and -100, it will scale to -0.5 to 0 and you will get no match other than 0 as the nearest neighbour. does it make sense? --- _[View the full topic](https://discourse.flucoma.org/t/iqr-ing-corpora/786)._
