ndlutil toolbox and the optimi toolbox. You can use your user name and password for accessing these toolboxes.
Current release is 0.14.
This toolbox allows computation of several different noise models and their gradients. You can add noise models to the toolbox by creating versions of the relevant files. Once added, they can be tested using the noiseTest. For example you can test the probit noise model by writing
>> noiseTest('probit')
There are several noise models implemented, the mains ones that are being maintained for the latest release are:
gaussian
ordered
probit
These noise models are Gaussian (standard Gaussian noise), probitistic regression for binary classificaiton and ordered categorical for ordered categories (ordinal regression).
