| Abstract: | : | Belief Change deals with how a belief state should be rationally modified in response to some observation made or evidence received. There are several related approaches to deal with different issues relevant to belief change. A body of knowledge could be a finite set or infinite, the modification method could be used on a one off basis or repeatedly, the body of knowledge could be probabilistic or non-probabilistic, the modification could involve removal of knowledge or addition of knowledge, and so on. There are some standard tools that are used in modifying a body of knowledge. The “selection†tool is possibly the best known among them. It comes in the form of a tie breaking mechanisms, and used mostly in the context of non-probabilistic belief change. In the probabilistic context we need two more tools, Retention and Distribution that will help with rational modification of probabilistic knowledge. In this talk I will briefly touch upon some ideas in this context. |
