Role of Logic in Cognitive Science

open access: yesStudia Humana, 2018
In their work McCulloch and Pitts describe an idea of representing all of nervous activity in terms of propositional logic. This idea was quickly challenged.

A Description Logic Framework for Commonsense Conceptual Combination Integrating Typicality, Probabilities and Cognitive Heuristics [PDF]

open access: yes, 2019
We propose a nonmonotonic Description Logic of typicality able to account for the phenomenon of concept combination of prototypical concepts. The proposed logic relies on the logic of typicality ALC TR, whose semantics is based on the notion of rational ...

Nonmonotonic Reasoning and Causation [PDF]

open access: yesCognitive Science, 1990
It is suggested that taking into account considerations that traditionally fall within the scope of computer science in general, and artificial intelligence in particular, sheds new light on the subject of causation. It is argued that adopting causal notions con be viewed as filling a computational need: They allow reasoning with incomplete information,

Reasoning about Minimal Belief and Negation as Failure

open access: yes, 2011
We investigate the problem of reasoning in the propositional fragment of MBNF, the logic of minimal belief and negation as failure introduced by Lifschitz, which can be considered as a unifying framework for several nonmonotonic formalisms, including ...

Nonmonotonic Reasoning

open access: yesJournal of Japan Society for Fuzzy Theory and Systems, 1992
The author gives an introductory survey of nonmonotonic reasoning and nonmonotonic logic, including circumscription, default logic, autoepistemic logic, application to a knowledge base and a truth maintenance system.

Optimizing the computation of overriding

open access: yes, 2015
We introduce optimization techniques for reasoning in DLN---a recently introduced family of nonmonotonic description logics whose characterizing features appear well-suited to model the applicative examples naturally arising in biomedical domains and ...

Integrating Non-monotonic Logical Reasoning and Inductive Learning With Deep Learning for Explainable Visual Question Answering

open access: yesFrontiers in Robotics and AI, 2019
State of the art algorithms for many pattern recognition problems rely on data-driven deep network models. Training these models requires a large labeled dataset and considerable computational resources. Also, it is difficult to understand the working of

The Complexity of Reasoning for Fragments of Default Logic [PDF]

open access: yes, 2009
Default logic was introduced by Reiter in 1980. In 1992, Gottlob classified the complexity of the extension existence problem for propositional default logic as $\SigmaPtwo$-complete, and the complexity of the credulous and skeptical reasoning problem as

The SP Theory of Intelligence: An Overview

open access: yesInformation, 2013
This article is an overview of the SP theory of intelligence, which aims to simplify and integrate concepts across artificial intelligence, mainstream computing and human perception and cognition, with information compression as a unifying theme.
