In the real world applications it is common that relationship between tuples of attributes of dimension higher than two need to be examined. It is well known that correlation analysis is focused on measuring of strength and direction of relationship between a pair of attributes. Algorithms using intercriteria analysis that solve the problem of measuring the strength of relationship between triples, quadruples, etc., were designed previously. The research presented in this paper is motivated by possibilities of using intuitionistic fuzzy equivalence relations to classify the data into the specific classes. The objective of this work is to use the values of correlation coefficients and compute the relationship between more than two attributes. The results are compared with the results obtained by intercriteria analysis.

In this paper, two procedures are proposed that transform intuitionistic fuzzy information into fuzzy information. Using the results obtained with the de-I-fuzzification procedures, formulas for intuitionistic fuzzy entropy are constructed.

This paper provides a holistic view of open-world machine learning by investigating class discovery, and class incremental learning under OWA. The challenges, principles, and limitations of current methodologies are discussed in detail. Finally, we position IFS over multiple universes as a formalism to capture the evolution in Big Data as part of incremental learning.

We use the natural properties of intuitionistic fuzzy sets (IFSs for short) to represent the pros, cons, and lack of knowledge concerning different options/alternatives, aiding in decision making, particularly in group decision making. We present a novel approach. We do not compare options/alternatives in pairs, we do not use distances. The approach is transparent and easily understandable for decision makers. The novel method points out the best option by ranking them.

In recent years, a new approach to the estimation of uncertainty in service systems has been developed. It is based on a causal characterization of the traffic in virtual service devices and makes use of the notion of an intuitionistic fuzzy pair. In a series of papers, this approach has been used to obtain quality of service estimations of various compositions of services. In the present paper, an overview of the main results related to the estimation of uncertainty in service compositions is presented.

The construction industry faces various challenges related to uncertainties in project bids and unstable pricing. These challenges include situations where uncertainties in bid documents can affect project pricing and performance. In order to resolve these uncertainties and clarify project requirements, risks and uncertainties within the document need to be identified early in the project life cycle. This study aims to rank the factors affecting project pricing. For this purpose, firstly, the parameters that have an impact on pricing are defined and then these factors are weighted by using Intuitionistic Fuzzy Analytic Hierarchy Process with Ordered Pairs. The analysis of factors affecting construction pricing reveals some important insights. Environmental uncertainties and uncertainties in prices and labor costs are the most important factors influencing pricing, while past project experience is the least important factor. Overall, these findings shed light on the multifaceted nature of construction pricing, which is shaped by the complex interaction of environmental, economic and market factors.

The research on intuitionistic fuzzy sets gives an extra dimension in mathematics. It has been observed that some operators including the modal operators have very interesting properties in intuitionistic fuzzy sets. More important properties are investigated in this paper and new findings are obtained and proved.

Intuitionistic fuzzy topological space and bitopological space have been introduced by using the concepts of intuitionistic fuzzy sets which are the generalizations of interval valued fuzzy sets. This paper commences by presenting the notion of intuitionistic fuzzy T0 in the context of bitopological spaces (IFB-T0). Subsequently, we explore various connections and relationships between these concepts. Then, we find out the relation between intuitionistic T0 and IFB-T0 spaces. Further, we investigated continuity between two IFB spaces.
