Fuzzy expert system

I want to start a fuzzy expert system design which has a risk classifier that takes into account whether a certain parameter increase the risk ordecrease,how do i start working with arduino controller :(``

What is it you're trying to develop? Most expert systems I am aware of require something approaching a PC in power (if not a high end PC, or multi-layer server system) in order to run well.

I suppose it could be done in some manner if you simplified the DB design (Something like the old Berkley DB), put the rules in the DB on an SD card, and made a really tight rule interpretor and analysis engine - or maybe a multi-Arduino setup.

This seems like the wrong platform to apply the problem to, unless you are needing one heck of challenge...

:)

Expert system over what ?
