A Quick Algorithm for Binary Discernibility Matrix Simplification using Deterministic Finite Automata

open access: yesInformation, 2018
The binary discernibility matrix, originally introduced by Felix and Ushio, is a binary matrix representation for storing discernible attributes that can distinguish different objects in decision systems. It is an effective approach for feature selection,

Incomplete Dominance-Based Intuitionistic Fuzzy Rough Sets and Their Application in Estimation of Inflation Rates in the Least Developed Countries

open access: yesIEEE Access, 2023
Although the concepts of imprecision are captured by both rough sets and intuitionistic fuzzy sets, investigations combining these two ideas and their applications in incompletely ordered information systems are scarce.

A Novel Approach to Generalized Intuitionistic Fuzzy Soft Sets and Its Application in Decision Support System

open access: yesMathematics, 2019
The basic idea underneath the generalized intuitionistic fuzzy soft set is very constructive in decision making, since it considers how to exploit an extra intuitionistic fuzzy input from the director to make up for any distortion in the information ...
