It's an approach to AI that allows you to generate rules based on probabilistic logic (0.0-1.0) rather than strictly boolean true/false (1 or 0). The applications are used in tons of different systems from medical diagnostics tools to washing machines. The plus side is that it allows you to make systems that can be tweaked using trial and error to handle cases that would require very complex logic otherwise. The down side is that alot of the time the systems aren't provable the way other types of logic are, and they can be a pain to debug.
