Conditional Inference and Activation of Knowledge Entities in ACT-R

  title={Conditional Inference and Activation of Knowledge Entities in ACT-R},
  author={Marco Wilhelm and Diana Howey and Gabriele Kern-Isberner and Kai Sauerwald and Christoph Beierle},
Activation-based conditional inference applies conditional reasoning to ACT-R, a cognitive architecture developed to formalize human reasoning. The idea of activation-based conditional inference is to determine a reasonable subset of a conditional belief base in order to draw inductive inferences in time. Central to activation-based conditional inference is the activation function which assigns to the conditionals in the belief base a degree of activation mainly based on the conditional’s…

Syntax Splitting = Relevance + Independence: New Postulates for Nonmonotonic Reasoning From Conditional Belief Bases

This paper analyzes inductive inference operators which, like system P, system Z, or the more recent c-inference, generate an inference relation from a conditional knowledge base, and axiomatizes the two aforementioned aspects of syntax splitting, relevance and independence, as properties of such induction inference operators.

The logic of conditionals

The standard use of the propositional calculus ('P.C.’) in analyzing the validity of inferences involving conditionals leads to fallacies, and the problem is to determine where P.C. may be ‘safely’

System Z: A Natural Ordering of Defaults with Tractable Applications to Nonmonotonic Reasoning

The Z-ordering is defined, two extensions are then described, maximum-entropy and conditional entailment, which trade in computational simplicity for semantic refinements.
