Modus Ponens Tollens for RU-Implications [PDF]

open access: yesInformation Processing and Management of Uncertainty in Knowledge-Based Systems18th International Conference, 2020
In fuzzy rules based systems, fuzzy implication functions are usually considered to model fuzzy conditionals and to perform forward and backward inferences. These processes are guaranteed by the fulfilment of the Modus Ponens and Modus Tollens properties by the fuzzy implication function with respect to the considered conjunction and fuzzy negation. In

MODUS PONENS AND MODUS TOLLENS: THEIR VALIDITY/INVALIDITY IN NATURAL LANGUAGE ARGUMENTS [PDF]

open access: yesStudies in Logic, Grammar and Rhetoric, 2017
The precedent studies on the validity of Modus ponens and Modus tollens have been carried out with most regard to a major type of conditionals in which the conditional clause is a sufficient condition for the main clause.

Generalized Modus Tollens with Linguistic Modifiers for Inverse Approximate Reasoning [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2014
Based on our previous researchs about generalized modus ponens (GMP) with linguistic modifiers for If … Then rules, this paper proposes new generalized modus tollens (GMT) inference rules with linguistic modifiers in linguistic many–valued ...

Reasoning With Conditionals About Everyday and Mathematical Concepts in Primary School [PDF]

open access: yesFrontiers in Psychology, 2020
A research link between conditional reasoning and mathematics has been reported only for late adolescents and adults, despite claims about the pivotal importance of conditional reasoning, i.e., reasoning with if–then statements, in mathematics. Secondary

A Fuzzy Take on the Logical Issues of Statistical Hypothesis Testing

open access: yesPhilosophies, 2021
Statistical Hypothesis Testing (SHT) is a class of inference methods whereby one makes use of empirical data to test a hypothesis and often emit a judgment about whether to reject it or not. In this paper, we focus on the logical aspect of this strategy,

Fuzzy Inference Full Implication Method Based on Single Valued Neutrosophic t-Representable t-Norm

open access: yesProceedings, 2022
As a generalization of intuitionistic fuzzy sets, single-valued neutrosophic sets have certain advantages for solving indeterminate and inconsistent information. In this paper, we study the fuzzy inference full implication method based on a single-valued

Modus tollens with respect to uninorms: U-Modus Tollens

open access: yesInternational Journal of Approximate Reasoning, 2020
In fuzzy logic and approximate reasoning the inference rule given by the Modus Tollens usually derives into an inequality involving three logical operators: a conjunction, an implication function and a negation. Until now, in this scenario the conjunction has been commonly modeled by a t-norm, but recently the possibility of using a more general ...

Critiques of Axiological Realism and Surrealism [PDF]

open access: yes, 2020
Lyons’s (2003, 2018) axiological realism holds that science pursues true theories. I object that despite its name, it is a variant of scientific antirealism, and is susceptible to all the problems with scientific antirealism.
