C code
-
The old
bigback Bayesian neural network simulator.
source code for bigback5.
information (not up to date).
I wrote bigback to develop and test the
ideas of my phd, for research purposes only. I used it to
make my winning entry in the prediction competition.
It can implement Bayesian methods for regression nets and
classifiers but is a research tool only.
Commercial users are asked to send a donation
to support my research
if they use this software.
Anyone interested in non-linear data modelling with
neural networks is encouraged to look into Gaussian processes.
-
Bigback has been used to create several Materials Modelling Algorithms.
See Materials Algorithms Project website
then go to Neural networks section
- macopt: A conjugate gradient optimizer that
I wrote, which only makes use of gradient information
and doesn't need a routine that returns the function value.
More information about
macopt.
- Free Energy Code
tar. (For decoding and cryptanalysis. Please contact
me before taking this code.)
- Software for simulation of MN codes and GL codes (almost the
best error correcting codes in the world!)
tar. (c) David MacKay and Radford Neal.
see also Radford Neal's software
- A couple of codes for use with the above MN/GL software
can be found here:
tar. Or you can get individual files here
directory. There are three files for each code: A, Cn and G.
A is the parity check matrix, and G is the generator matrix.

Perl code
I have written tons of perl programs, which you can find
here. All supplied without warranty.
