A Combination of Fuzzy Techniques and Chow Test to Detect Structural Breaks in Time Series
Axioms, 2023 In a series of papers, we suggested a non-statistical method for the detection of structural breaks in a time series. It is based on the applications of special fuzzy modeling methods, namely Fuzzy transform (F-transform) and selected methods of Fuzzy ...

Preimage Problem Inspired by the F-Transform
Mathematics, 2022 In this article, we focus on discrete data processing. We propose to use the concept of closeness, which is less restrictive than a metric, to describe a certain relationship between objects.

Continuous Fuzzy Transform as Integral Operator [PDF]
IEEE transactions on fuzzy systems, 2020 The fuzzy transform (F-transform) is ubiquitous in different research fields and applications, such as image and data compression, data mining, knowledge discovery, and the analysis of linguistic expressions.

On the Similarity and Dependence of Time Series
Mathematics, 2021 In this paper, we undertake the problem of evaluating interrelation among time series. Interrelation is measured using a similarity index. In this paper, we suggest a new one based on the known fuzzy transform (F-transform), which has been proven to ...

Journal of Computing Research and Innovation, 2022 Laplace transforms play an essential role in the analysis of classical non-Markovian queueing systems. The problem addressed here is whether the Laplace transform approach is still valid for determining the characteristics of such a system in a fuzzy ...

Semiring-Valued Fuzzy Sets and F-Transform
Mathematics, 2021 The notion of a semiring-valued fuzzy set is introduced for special commutative partially pre-ordered semirings, including basic operations with these fuzzy structures. It is showed that many standard MV-algebra-valued fuzzy type structures with standard

Solving Intuitionistic Fuzzy Transport Equations by Intuitionistic Fuzzy Laplace Transforms [PDF]
ITM Web of Conferences, 2022 In this paper, we use an intuitionistic fuzzy Laplace transforms for solving intuitionistic fuzzy hyperbolic equations precisely the transport equation with intuitionistic fuzzy data under strongly generalized H-differentiability concept.

Bitcoin Analysis and Forecasting through Fuzzy Transform
Axioms, 2020 Sentiment analysis to characterize the properties of Bitcoin prices and their forecasting is here developed thanks to the capability of the Fuzzy Transform (F-transform for short) to capture stylized facts and mutual connections between time series with ...
