Talk:Deconvolution/2D+
I got interested in higher dimensional deconvolution as a way of looking for trading indicators in financial time series. I set this task as an example of something that I'm speculating can be done well with functional and array processing languages, but only with difficulty otherwise, which I hope someone will weigh in to confirm or refute. In case anyone wants to know, consistent test data were generated partly by this higher dimensional convolution function,
<lang Ursala>conv = +^|(~&x+,*DrlDSNiCK9xxSNiCK9K7iFS+ *)=>times+ **+ *K7|\x+ iota; * ! plus:-0</lang>
invoked as (conv d)(h,f)
with dimension d > 0
and conforming h
and f
. I suggest a development methodology based on warming up with Deconvolution/1D, then hand coding the solutions for the next few dimensions, and then looking for the pattern.
