Defaults and Infinitesimals: Defeasible Inference by Nonarchimedean Entropy-Maximization (1302.4988v1)
Published 20 Feb 2013 in cs.AI
Abstract: We develop a new semantics for defeasible inference based on extended probability measures allowed to take infinitesimal values, on the interpretation of defaults as generalized conditional probability constraints and on a preferred-model implementation of entropy maximization.
