For the initial training, I generated more than 20000 examples by mapping a simple xwindow program and noting the input parameters and the position returned by 'Smart' in a file each time. For the online training, well, it can converge to something only if the user is consistent (and after "some" time, I deliberately put a very small learning rate), and otherwise it'll just give not quite random answers... > What about using a partial recurrent network (Jordan/Elman)?

IMHO MLP can't do so because they are feedforward only. Because I don't know what a Jordan/Elman network is! I just implemented what we saw in the NN course, and we didn't learn those 2 structures (yet?). Could you please give me information, or a pointer to it, concerning Jordan/ Elman networks (possibly off-list)? And anyway, it would be better to take into account where the last window ended up (possibly after the user moved it), and not only where it was placed. BTW, it reminds me that I should also take into account where the topmost window is... Cheers, Nicolas -- Life is a sexually transmitted fatal disease. (W. Allen?)
