Optimal scale selection based on multi-scale single-valued neutrosophic decision-theoretic rough set with cost-sensitivity
The selection of optimal scale has always been the essential problem of multi-scale system. However, most of the current studies only consider the consistency of the system, and ignore the cost information. Therefore, based on the ...
Fuzzy simulations and bisimulations between fuzzy automata
Simulations and bisimulations between two fuzzy automata over a complete residuated lattice were defined by Ćirić et al. (2012) [7,8] as fuzzy relations between the sets of states of the automata. However, they act as a crisp ...
Lexicon-based sentiment analysis in texts using Formal Concept Analysis
In this paper, we present a novel approach for sentiment analysis that uses Formal Concept Analysis (FCA) to create dictionaries for classification. Unlike other methods that rely on pre-defined lexicons, our approach allows for the ...
Powerset operators induced by fuzzy relations as a basis for fuzzification of various mathematical structures
We propose a unified approach to the theory of forward and backward powerset operators induced by fuzzy relations with special attention to the algebraic and topological properties of these operators. On the basis of this theory, we ...
Explaining black-box classifiers: Properties and functions
Explaining black-box classification models is a hot topic in AI, with the overall goal of improving trust in decisions made by such models. Several works have been done and diverse functions have been proposed. However, their formal ...
On manipulation in merging epistemic states
In this work we study the problem of manipulation in the framework of merging complex epistemic states. We adopt the techniques concerning representation and impossibility in merging complex epistemic states proposed by Mata Díaz and ...
Three-way approximation of decision granules based on the rough set approach
We discuss the three-way rough set based approach for approximation of decision granules in Intelligent Systems (IS's). The novelty of the approach is in presenting a new concept of approximation space which is based on advanced ...
