Monotonic and Non-Monotonic Reasoning in artificial intelligence in hindi | #23

Contact : wellacademy4343@gmail.com The definite clause logic is monotonic in the sense that anything that could be concluded before a clause is added can still be concluded after it is added; adding knowledge does not reduce the set of propositions that can be derived. A logic is non-monotonic if some conclusions can be invalidated by adding more knowledge. The logic of definite clauses with negation as failure is non-monotonic. Non-monotonic reasoning is useful for representing defaults. A default is a rule that can be used unless it overridden by an exception. Example : let the KB contain: birds fly . Penguin cannot fly. Tweety is a bird. However if the following information is added to KB Tweety is a penguin the previous conclusion must be retracted and,instead, the new conclusion that Tweety does not fly will hold.
