Overview

Top Research Topics at Fuzzy Sets and Systems?

The journal focuses largely on the fields of Fuzzy logic, Fuzzy set, Discrete mathematics, Fuzzy number and Fuzzy set operations. Research in Fuzzy logic discussed is concerned with the study of Artificial intelligence as a whole. While it focused on Artificial intelligence, it was also able to explore topics like Machine learning and Pattern recognition.

In addition to Fuzzy set research, it aims to explore topics under Algorithm, Data mining, Applied mathematics and Information processing. Topics in Discrete mathematics were tackled in line with various other fields like T-norm, Set (abstract data type), Pure mathematics and Combinatorics. The Fuzzy number study featured in the journal draws connections with the study of Fuzzy classification.

Fuzzy measure theory is a focus of the Fuzzy classification works in Fuzzy Sets and Systems. Most of the works presented in Fuzzy Sets and Systems deals with Fuzzy set operations but it intersects with the subject of Neuro-fuzzy. In particular, the Fuzzy control system works presented emphasize discussions on Adaptive neuro fuzzy inference system.

  • Fuzzy logic (51.23%)

Research areas of the most cited articles at Fuzzy Sets and Systems:

The journal articles are organized to reinforce research efforts on Fuzzy logic, Fuzzy set, Fuzzy number, Fuzzy set operations and Fuzzy classification. The journal papers facilitate discussions on Fuzzy logic that incorporate concepts from other fields like Algorithm and Mathematical optimization. While the primary focus in the most cited publications is Fuzzy set, they also dissect topics surrounding Discrete mathematics and Algebra, T-norm and Pure mathematics as a whole.

What topics the last edition of the journal is best known for?

  • Artificial intelligence
  • Statistics
  • Machine learning

The previous edition focused in particular on these issues:

Fuzzy Sets and Systems primarily tackles Fuzzy logic, Pure mathematics, Fuzzy set, Function (mathematics) and Applied mathematics. The Fuzzy logic study tackling the subject of Fuzzy number is the focus of the journal. Aside from discussions in Pure mathematics, the journal also deals with the subject of Class (set theory) which intersects with Generalization disciplines.

The research on Fuzzy set discussed in it draws on the closely related field of Discrete mathematics. The work tackled in the journal goes beyond the discipline of Function (mathematics) as it also encompasses Differentiable function. Control theory, Nonlinear system, Fuzzy control system, Lyapunov function and Stability (learning theory) are among the areas of Control theory tackled.

The most cited articles from the last journal are:

  • Finite-time synchronization of multi-coupling stochastic fuzzy neural networks with mixed delays via feedback control (19 citations)
  • New results on pseudo almost periodic solutions of quaternion-valued fuzzy cellular neural networks with delays (19 citations)
  • Fuzzy wavelet neural control with improved prescribed performance for MEMS gyroscope subject to input quantization (18 citations)

Publication chance based on affiliation

The publication chance index shows the ratio of articles published by the best research institutions in the journal edition to all articles published within that journal. The best research institutions were selected based on the largest number of articles published during all editions of the journal.

The chart below presents the percentage ratio of articles from top institutions (based on their ranking of total papers).Top affiliations were grouped by their rank into the following tiers: top 1-10, top 11-20, top 21-50, and top 51+. Only articles with a recognized affiliation are considered.

During the most recent 2021 edition, 3.89% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 15.61% were posted by at least one author from the top 10 institutions publishing in the journal. Another 4.34% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 13.58% of all publications and 66.47% were from other institutions.

Returning Authors Index

A very common phenomenon observed among researchers publishing scientific articles is the intentional selection of journals they have already attended in the past. In particular, it is worth analyzing the case when the authors participate in the same journal from year to year.

The Returning Authors Index presented below illustrates the ratio of authors who participated in both a given as well as the previous edition of the journal in relation to all participants in a given year.

Returning Institution Index

The graph below shows the Returning Institution Index, illustrating the ratio of institutions that participated in both a given and the previous edition of the conference in relation to all affiliations present in a given year.

The experience to innovation index

Our experience to innovation index was created to show a cross-section of the experience level of authors publishing in a journal. The index includes the authors publishing at the last edition of a journal, grouped by total number of publications throughout their academic career (P) and the total number of citations of these publications ever received (C).

The group intervals were selected empirically to best show the diversity of the authors' experiences, their labels were selected as a convenience, not as judgment. The authors were divided into the following groups:

  • Novice - P < 5 or C < 25 (the number of publications less than 5 or the number of citations less than 25),
  • Competent - P < 10 or C < 100 (the number of publications less than 10 or the number of citations less than 100),
  • Experienced - P < 25 or C < 625 (the number of publications less than 25 or the number of citations less than 625),
  • Master - P < 50 or C < 2500 (the number of publications less than 50 or the number of citations less than 2500),
  • Star - P ≥ 50 and C ≥ 2500 (both the number of publications greater than 50 and the number of citations greater than 2500).

The chart below illustrates experience levels of first authors in cases of publications with multiple authors.
