I am tring to use dd_tools to do svdd calssification .I do not know how to get the result.please help who is familiar with dd_tools.
a = gendatb([30 30]);
% make the second class the target class and change the labels:
a = oc_set(a,'1');
% only use target class:
a = target_class(a);
% generate test data:
b = oc_set(gendatb(200),'1');
% train svdd
w=svdd(a,0.1,3);
%test svdd
c=b*w.
how can I see the result of c.i.e. the labels of c. for example, the real labels of c is 1 1 -1 -1 . the output is 1 1 1 1,so that i know that c_3 and c_4 was classified into wrong class.
