By AI, of course, I mean Artificial Intelligence. I'm really interested in all subjects pertaining to the inner workings and abilities of a human consciousness. So this also includes cognitive science, neuroscience, and of course philosophy.
I am a strong proponent of the idea of strong AI - the hypothesis that a computer running the correct program is a mind, in all its glory and subtlety.
One holey argument against strong AI is the Chinese room argument of John Searle.
I am also interested in machine learning and use of genetic algorithms toward that goal. I have implemented several genetic algorithms, perhaps most noteworthy of which is the checkers project (which, just to cut to the chase, did not have excellent results, due to it ran too slowly I believe).
