Product of Two Fuzzy Normed Spaces and its Completion [PDF]

Engineering and Technology Journal, 2012
The aim of this paper is to prove that the Cartesian product of two complete fuzzy normed space is again a complete fuzzy normed space. Also to prove that the Cartesian product of two complete fuzzy inner product spaces is a complete fuzzy inner product ...

On Fuzzy Soft Linear Operators in Fuzzy Soft Hilbert Spaces

Abstract and Applied Analysis, 2020
Due to the difficulty of representing problem parameters fuzziness using the soft set theory, the fuzzy soft set is regarded to be more general and flexible than using the soft set.

On fuzzy n-inner product spaces [PDF]

AIP Conference Proceedings, 2017
In this paper, first we show that every n-inner product space can be reduced to (n-1) inner product space. Then we construct a new concept of fuzzy n-inner product space. Furthermore, we show that every fuzzy n-inner product space can be reduced to fuzzy (n-1) inner product space.

A block matrix incremental feature selection method based on fuzzy rough minimum classification error

Scientific Reports
In fuzzy rough set models, inner-product correlation serves as an effective evaluation function for feature selection, with its key advantage lying in its ability to characterize the minimum classification error inherent in the model.

On Semi-Vector Spaces and Semi-Algebras with Applications in Fuzzy Automata

Axioms
In this paper, we expand the theory of semi-vector spaces and semi-algebras, both over the semi-field of nonnegative real numbers R0+. More precisely, we prove several new results concerning these theories.

A Proposed Speaker Recognition Method Based on Long-Term Voice Features and Fuzzy Logic [PDF]

Engineering and Technology Journal, 2021
Speaker recognition depends on specific predefined steps. The most important steps are feature extraction and features matching. In addition, the category of the speaker voice features has an impact on the recognition process.
