Exceptional Subclasses in Qualitative Probability
System z+ [Goldszmidt and Pearl, 1991, Goldszmidt, 1992] is a formalism for reason ing with normality defaults of the form "typ ically if 'f' then 1/; (with strength .5)" where {j is a positive integer. The system has a critical shortcoming in that it does not sanction inheritance across exceptional sub classes. In this paper we propose an exten sion to System z+ that rectifies this short ...
متن کاملProbabilsitic semantics and defaults
There is much interest in providing proba-· bilistic semantics for defaults but most ap proaches seem to suffer from one of two prob lems: either they require numbers, a problem defaults were intended to avoid, or they gen erate peculiar side effects. Rather than provide semantics to defaults, we address the original problem that defaults were intended to solve: that of reasoning un der unc...
متن کاملRepresenting and Reasoning with Defaults for Learning Agent
The challenge we address is to create autonomous, inductively learning agents that exploit and modify a knowledge base. Our general approach, embodied in a continuing research program (joint with Stuart Russell), is declarative bias, i.e., to use declarative knowledge to constrain the hypothesis space in inductive learning. In previous work, we have shown that many kinds of declarative bias can...

متن کاملCausal Default Reasoning: Principles and Algorithms
The minimal model semantics is a natural interpretation of defaults yet it often yields a behavior that is too weak. This weakness has been traced to the inabiity of minimal models to reflect certain implicit preferences among defaults, in particular, preferences for defaults grounded on more ‘specific’ information and preferences arising in causal domains. Recently, ‘specificity’ preferences h...
