Line 204 in fixedcc.m function :

Should it be replaced by ?
par = w.data{4};

Thank you for your help.

]]> nusvc Does not work tag:perclass.com,2011:index.php/forums/viewthread/.340 2011-08-17T08:47:50Z ChadZ1 Example 1:
nusvc([],’p’,1,.1)

generates error due to nu parameter being supplied, but documentation says this should work.

Example 2:
nusvc(dataset(randn(10,3), [ones(5,1);zeros(5,1)]), ‘p’, 1);

generates error as well.

This is on PRTools version 4.1.12

Frustrating…

]]> Small inconsistency in the documentation tag:perclass.com,2011:index.php/forums/viewthread/.317 2011-06-14T13:44:13Z Jean-Michel Dear PRSD Team,

Two minor remarks about Section 9.5.1 in the latest documentation:

1) the “t” of “fruit” is missing in the 4th sentence,
2) In the last line just before Section 9.5.2, I noticed that you’re mentioning a non-cancer classe while demonstrating with the fruit dataset. (I hope I understood correctly :-))

Cheers,

]]> Randomly selecting only one sample from the whole dataset tag:perclass.com,2011:index.php/forums/viewthread/.298 2011-04-08T11:58:07Z Jean-Michel Hello,

Using randsubset I can select 1 sample per class but not 1 sample out of the whole dataset.

Actually, I do not know yet if it is a misuse or a bug...Could somebody help me?

]]> Size of index arrays returned by the subset function tag:perclass.com,2011:index.php/forums/viewthread/.279 2011-01-03T14:54:54Z Jean-Michel Hello,

I noticed that the (index array) output arguments in sddata/subset have inconsistent sizes.

[B,REST,IND,IND2]=subset(A,CLASSES)

While IND is a row vector, IND2 is generally a columns vector.
Example:

>> [r,s,Ir,Is] = subset(a.a,'class','apple');
>> a = load('fruit');
>> [r,s,Ir,Is] = subset(a.a,'class','apple');
>> r
'Fruit set' 100 by 2 sddata, class: 'apple'
>> s
'Fruit set' 160 by 2 sddata, 2 classes: 'banana'(100) 'stone'(60) 
>> size(Ir)

ans =

   100     1

>> size(Is)

ans =

     1   160

Is there a reason for that?

Cheers

]]> Error with ASAM tag:perclass.com,2010:index.php/forums/viewthread/.272 2010-12-24T12:51:09Z Jean-Michel Hi,

Actually I do not know if it is a bug or my mistake.

When training my GMM on my dataset obtained from dataset*sdprox(dataset(proto),’sam’) everything goes smoothly but if I change to ‘asam’ then the learning fails.

Any idea of what it is?
