function nb = nobias(ker) %NOBIAS returns true if SVM kernel has no implicit bias % % Usage: nb = nobias(ker) % % Parameters: ker - kernel type % % Author: Steve Gunn (srg@ecs.soton.ac.uk) if (nargin ~= 1) % check correct number of arguments help nobias else switch lower(ker) case {'linear','sigmoid'} %,'anovaspline1','anovaspline2','anovaspline3'} nb = 1; otherwise nb = 0; end end
