** What is this program?
This is the source code of my reservoir computing model presented in
the following paper:
Tadashi Yamazaki and Shigeru Tanaka,
Robust Reservoir Generation by Correlation-Based Learning,

This is an open access article so that anyone can download the PDF
from the above link.
The model can be run online at the sim.neuinf.jp simulation platform:
** Files
This folder contains the following files:
README :: This file
Makefile :: Makefile
main.c :: The simulation program
xcorr.c :: The program to calculate a similarity index
mt19937ar-cok.c :: The Mersenne Twister pseudo random number generator (*)
w.0.bz2 :: Initial connection weights (expand first by % bunzip2 w.0.bz2)

** Usage
1. % make
2. % ./main 3 o w.0 w.1 33
3. % xcorr o.a o.a c
#1 generates main and xcorr binaries.
#2 generates o.a, o.r, and w.1. File o.a is used to compute a similarity
index. File o.r is used to obtain a raster plot. For example, using
GNUPLOT, we do:
% gnuplot
gnuplot> plot [0:1000][0:100] 'o.r' w d
to plot the activity of the first 100 neurons for 1000 steps. File w.1
is the updated connection weights from the initial weights specified by
w.0. The 1st arg (3) is the random number seed for random connections
from excitatory to inhibitory neurons, so that this arg is fixed during
repeated trials. The last arg (33) is the seed for temporal afferent
noise, so that this arg should change across trials. See usage by just
% ./main.
#3 generates c.png, c.si, c.d, the similarity index, from file o.a.
File c.png is the PNG file of the whole index matrix (Eq. 6).
File c.si contains the average and the standard deviation of the index
with the following format:
