PCA, Source analysis and Unmixing, environmental forensics
I am using R for environmental forensics (determination of the sources
and/or groupings in mixtures of organic chemicals in the field). The
goal is to determine in there are groups of samples with
similar/dissimilar compositions, and to assign samples to a potential
source or a mixture of sources based on the composition (unmixing and
source allocation). Typically there are 10 to 50 chemicals that

Optimization of constrained linear least-squares problem
Dear R-ians,
I want to perform an linear unmixing of image pixels in fractions of
pure endmembers. Therefore I need to perform a constrained linear
least-squares problem that looks like :
min || Cx - d || ? where sum(x) = 1.
I have a 3x3 matrix C, containing the values for endmembers and I have a
3x1 column vector d (for every pixel in the image). In theory my x
values should all be in the

Polytopic Vector Analysis (PVA)
I am curious whether anybody has or is developing this capability within
R. I have not found any software yet that has this capability and I am
not sure whether it is too new a method and nobody is actually using it,
or if there are other means to get the same analysis that I do not know
of. Any information regarding developments or use of this method would
be helpful.

Manual scratch allocation : memory usage doubt
Hi,
I am currently encoding 32 Khz/Qual-10/UWB encode mode, with
MANUAL_ALLOC enabled ( similar to the c5x/c6x configuration).
In file sb_celp.c, I noticed the scratch memory grow during
recursive (UWB -> WB) calls to 'sb_encode'.

perception of graphical data
Hello,
I apologize that this is off-topic. I am seeking information on
perception of graphical data, in an effort to improve the plots I
produce. Would anyone point me to literature reviews in this area? (Or
keywords to try on google?) Is this located somewhere near cognitive
science, psychology, human factors research?
For example, some specific questions I have are:

Speex newbie questions
Hi everyone,
I have got some questions about Speex, I am sorry if my questions are too
newbie:
1. For the LP analysis, did Speex use the AR (Autoregressive) model or the
ARMA model?
2. Am I right to say that Speex use a multistage VQ (since I believe Speex
employs two or more VQ consecutively - based on the manual it says that
Speex uses dynamically selectable codebooks (linear

Using GIMP on Centos-7, problem
Wondering if anyone here has ever tried installing this
https://github.com/bootchk/resynthesizer
as a gimp plugin in Centos-7, with gimp 2.8.16??
I find the installation instructions (for the binary tarball) are
minimal and whatever I do, it doesn't seem to appear in the gimp
menus, as it should.
I've used an older version (0.14) from years ago in older versions
of gimp, but how does

WinXP, R-2.9.1
LS.,
I have been trying to solve a (for me) tricky issue. No matter what I've
tried, I just can't find a way to do this.
This is the issue:
I have a text file (ansi text) "titles.txt" with lines of text; here is
an example of such a file:

I think you will get more trouble because this plugin uses python2 code
and I am not sure if this is supported under EL9.
You could try the flatpak version of this plugin ...

where is glib-devl x86-64?
I have a brand new installation of Rocky Linux 9.1 (I know, this isn't a
Rocky mailing list, but I can't find anything on this on Rocky forums, etc.
so I figured I would ask here),
and I installed Gimp, and would like to install the Resynthesizer plugin
package.
Trying to compile it from source, autogen.sh complains that I don't have
the gimp development libraries installed. In fact,

where is glib-devl x86-64?
I dunno. I guess it could be. Went to the Gimp site and saw that glib-devel
was mentioned there.
My tired old brain is a bit confused by this, since most other -devel
packages put -devel following the program/package name, and gimp doesn't.
I'll give that a try, though, to see if it takes care of my issue. Thanks!

beta2?
The debian vorbis-tools package is labeled version 1.0beta2-1 - does this
mean that better compression for stereo has been implemented? (I forgot
what the correct term for this was.) I am waiting with a couple of CD's I
would have ripped and made mp3's of (I don't have a multi-cd shuttle in
my laptop... ;), so that I can rather make ogg files, but I don't want to
make them now and

PLC in Speex-
I've been working on improving packet loss concealment in my VoIP client --
I hadn't actually realized speex performed some PLC until I was looking at
nb_decode().
There are two things I'd like to do, and I think both will require some
modification to nb_decode() and nb_decode_lost().

Speex on TI C6x, Problem with TI C5x Patch
Hi Jean-Marc, Hi Jim,
I have also seen some problems with the 1.1.8 release on the C55x. So far I
have boiled down the issues to the following:
1) We need our own "fixed_xx.h" header file. I don't know why, and haven't
had time to investigate, but there is a definite improvement when I use the
attached fixed_c55x.h file which has turned all the maths into inline
functions.
