This kind of statement is too vague to be useful. I even know all the words in there and I still don't know what you mean.

Your earlier post comes off as link-spam, as it uses general language to connect something tangentially related to what you're interested in to drive traffic to your website. This is not conducive to questions.

I know and use wavelet, Fourier, and other transforms on a daily basis, but your post did not stimulate any interest in me. Also, your reply on the other thread does not strike me as particularly insightful (I'd argue that your 'frequency decomposition' interpretation is flat-out wrong).

Are you familiar with the partition function?
