Re: Genetic Algorith Classification

[George Kousiouris]

hi,

I have used both (Matlab and Octave) ga packages, from experience the 
options are pretty much the same (so you can get an idea of them from 
matlab docs). But there are also some differences, mainly in the way the 
population is created and passed in the internal function in each case. 
AFAICR, one tool passed the entire population as an array (so you should 
handle the iteration over the population members inside the internal 
script that calculates the function) while the other passed the 
population member by member.

Furthermore, beware that Octave's ga version seemed to lose after some 
generations (at least in the version i used 3-4 years ago) the ability 
to limit the created population members values to a fixed normalized 
interval e.g. 0-1.

And a general question: are you sure you can use GA's for 
classification? I have not heard of such a use case before, GA's are 
normally used for optimization purposes. If you want classification, you 
can look at Artificial Neural Networks, Support Vector Machines etc.

BR,
George
