uncertainty in AI
Author
Hello ,
I'm looking for a way to apply uncertainty in a real application ..
I know Bayesian aka belief nets and Java ..
I just dont know how to combine them ,is there any book useful for this ?or at least online material ?
any ideas ?
thanx ..
I don't know anything about belief nets, but maybe you could use them to determine the fitness of a node in a neural network?
If you're new to genetic algorithms and neural nets, ai-junkie has a decent primer.
One highly-recommended book that I've been meaning to buy is Programming Game AI by Example. It supposed to talk about fuzzy logic, and might get you close to implementing belief nets.

Yes, some form of Bayesian inference is usually the best way of handling uncertainty. The next problem is what you do with that information on the other end, though.
Perhaps a better description of your problem?

If you just want the AI to be a bit less logical with it's choices, rand is all you need.
Usually when making a decision, you use some heuristic to weigh up all the options, then pick the best one. Before picking the best one, add a random number (within a reasonable range - e.g. 10% of the weighting range) to each of the weights. Now if there's a few "good options", the AI will choose from any of them, instead of always taking the very best option.
yeah, it was my mistake to answer a topic I know nothing about, but I figure my answer is as good as any when someone asks how to "combine" belief nets and Java. :) How do I combine game design with Python? forgive me for the snarky remarks, im sleepy.

Whoa... chapters 12-16 of my book! ;-)
Anyway, that's the thing we need to clarify. Is he asking about dealing with uncertain information for input or trying to create varied results?
