21 Mar 2014 Netlab Pattern analysis toolbox. Author: Ian Nabney Watson, Todd

I used this toolbox successfully with Matlab R2013a. It is very beneficial to have the book referenced in the above description. My application was classification of sounds in a trained NN into one of several categories. here are a few notes from my specific application:

Activation Functions Investigated
Linear – simplest, gives good results
Softmax – best general purpose for 1 of N classification
Logistic – good for binary classifications

Optimization Methods
Conjugate gradient descent – worst performing method
Scaled conjugate gradient descent (SCG) – sometimes superior
Quasi-Newton – gives most consistent results for current data set

Search for best number of hidden units
Smaller number runs faster/simpler
Larger number may provide more accurate results with the possibility of over-fitting the available data

Current data set, with 4 possible sound classifications, gave best result with about 15 hidden units

I also tried using a support vector machine for the same application and it performed slightly better.

hmmm.... no documentation, and the first demo I run fails due to an incompatibility with more recent version of MATLAB. Last update was 2002... I say this submission is dead.

I don't feel it is fully tested. So, you can't use it "off the shelf".
