gotta a big strong stopping associated with "trend quickly and reliably to" might relate to stopping fast AI very strong

but i got more optimization and tech techniques from the stopping :)
new stuff: if you want to find a signal with a known kind of mixing, you can use _all_ the metrics you have that identify the signal (for FastICA the gaussianness is minimized to desum the signals, summed signals are more gaussian) and mathematically look at how the numbers of that metric directly relate to the mixing parameters (the derivative for example, somewhat corrupt lost part) to "invert" it.
hard to say straight
but the positivity is helpfup for trying to continue, got a really big stop though :s

termux closed unsure where or if my draft is ... hmm they must be temporary editor files
i'm at https://web.archive.org/web/20260419233218/http://research.ics.aalto.fi/ica/... . first i went to wikipedia and found a paper introducing fastica and followed its footnote.

[fill-in: so, let's get a copy of fastica]
i ended up going to https://github.com/derekharrison/fastICA_C . it looks more familiar to me (which also means more triggering and challenging i'm afraid) and may be the actual code i started working off of (although the dates now don't seem to line up it could still work out as we had a lot of timestamp falsification going on) [but i think the one i had had more documentation could be wrong tho]

let's draft a buildfile, a makefile. hrm this might take me a bit. patsubst? wildcard?
CFLAGS=-Iinc fastica: $(patsubst %.c,%.o,$(wildcard src/*.c)) libfastica.a libfastica.a: $(patsubst %.c,%.o,$(wildcard lib/*.c))
i may need more things specified too

here's where i'm at. i'll ask a business AI why my static library can't use the the c standard library.
