Updating information based on generalized credal sets. Part 1: Finite case
This paper considers updating information and statistical inference based on generalized credal sets. In the first part, we define possible ways of conditioning for generalized credal sets in a finite setting, and its realization based on ...
Katětov-Tong insertion theorem for functions with values in a tensor product of complete lattices
It is shown that Katětov-Tong insertion theorem continues to hold for normal L-topological spaces and functions with values in appropriately L-topologized tensor product M ⊗ L where L is a complete lattice with an order-reversing involution and M ...
Necessary and sufficient conditions for the existence of fuzzy doubly strong equilibria in generalized fuzzy games
The concept of doubly strong equilibrium is a refinement of the concept of strong Nash equilibrium which represents the most desirable situations for generalized games, where all players get the best among the available outcomes. In this paper, ...
A note on representations of the Choquet integral via bases and transforms
In this note, we discuss the validity of formula (4.54) in Grabisch's book from 2016. This equation expresses the Choquet integral of nonnegative functions w.r.t. a game in the form of linear invertible transform of set functions. However, the ...
Multigranulation fuzzy probabilistic rough sets induced by overlap functions and their applications
As we all know, t-norms can be used to construct fuzzy probabilistic rough set (FPRS). Meanwhile, overlap functions (OFs), as a sort of novel aggregation functions different from t-norms, have shown a flourishing situation in terms of ...

Minimizing fuzzy interpretations in fuzzy description logics by using crisp bisimulations
The problem of minimizing finite fuzzy interpretations in fuzzy description logics (FDLs) is worth studying. For example, the structure of a fuzzy/weighted social network can be treated as a fuzzy interpretation in FDLs, where actors are ...
Simplification of ANFIS based on importance-confidence-similarity measures
Adaptive-network-based fuzzy inference system (ANFIS) is a well-known neuro-fuzzy system, which is widely implemented in nonlinear system approximation, prediction, control, and pattern classification. However, either too many fuzzy sets or fuzzy ...
Robust hybrid learning approach for adaptive neuro-fuzzy inference systems
The Adaptive Neuro-Fuzzy Inference System (ANFIS) is a regression model that uses fuzzy logic and neural networks, making it suitable for modeling the uncertainty of regression problems. However, the non-robust loss function in ANFIS's hybrid ...
Highlights
- Introduce a new version of the hybrid learning algorithm for Adaptive Neuro-Fuzzy Inference Systems.
- Emphasis on the significance of using different loss functions for parameter optimization.

Online sequential type-2 fuzzy wavelet extreme learning machine: A nonlinear observer application
The aim of this paper is to combine the time-frequency attributes of wavelets and neural network learning ability besides approximate reasoning features of type 2- fuzzy systems, and the advantages of online sequential extreme learning machine (...
Uninorms on bounded trellises
In this paper, we construct uninorms on a bounded trellis based on t-(co)norms on a ∧ ( ∨ )-semi-trellis and closure (interior) operators. The key is how to ensure the monotonicity of the constructed binary operation, which is closely related to ...
The median under orness
Besides the mean, the median is the most widely used single-valued descriptor of data sets. It is well-known that the orness level of the median operator is 1/2. In this paper we provide approximations of the median operator under a given level ...
The fuzzy degree of nondensifiability and applications
We introduce the notion of fuzzy degree of nondensifiability (FDND for short) as a non-negative real number that measures the Hausdorff distance between a bounded set of a fuzzy metric space and its closest Peano continuum. The FDND allows us to ...
A new approach to the fractional Abel k−integral equations and linear fractional differential equations in a fuzzy environment
This paper introduces some recent approaches to the fuzzy fractional Abel integral equations with respect to another function, which is called the fuzzy fractional Abel k−integral equations. The problem proposed here allows for the interpolation ...
