I would like to make a simple neural net with one or two layers of hidden units to implement some experiments I'm doing. It doesn't seem like it would be that tough to do in rev/meta. I was thinking of just using lines in a field/variable to represent each node, with the rest of the information contained in various hierarchical items in the lines, but perhaps there is a better way of doing it or someone already has something finished that they could share. Anyone? mark mitchell Japan _______________________________________________ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution
