In the rough fuzzy set theory, the rough degree is used to characterize the uncertainty of a fuzzy set, and the rough entropy of a knowledge is used to depict the roughness of a rough classification.

Fuzzy Entropy-assisted Fuzzy-Rough Feature Selection [PDF]
Feature selection (FS) is a dimensionality reduction technique that aims to select a subset of the original features of a dataset which offer the most useful information. The benefits of feature selection include improved data visualisation, transparency, reduction in training and utilisation times and improved prediction performance.

Finding fuzzy-rough reducts with fuzzy entropy [PDF]
Dataset dimensionality is undoubtedly the single most significant obstacle which exasperates any attempt to apply effective computational intelligence techniques to problem domains. In order to address this problem a technique which reduces dimensionality is employed prior to the application of any classification learning.

Fuzzy entropy and image thresholding are the most direct and effective methods for image segmentation. This paper, taking fuzzy Kapur's entropy as the optimal objective function, with modified discrete Grey wolf optimizer (GWO) as the tool, uses ...

Different Types of Entropy Measures for Type-2 Fuzzy Sets
In this work, we consider De Luca and Termini’s notion of non-probabilistic entropy, and we extend some entropy-like measures of the degree of fuzziness to type-2 fuzzy sets.

Perceptual Copyright Protection Using Multiresolution Wavelet-Based Watermarking And Fuzzy Logic
In this paper, an efficiently DWT-based watermarking technique is proposed to embed signatures in images to attest the owner identification and discourage the unauthorized copying.

Time dependence of entanglement entropy on the fuzzy sphere
We numerically study the behaviour of entanglement entropy for a free scalar field on the noncommutative ("fuzzy") sphere after a mass quench. It is known that the entanglement entropy before a quench violates the usual area law due to the non-local ...

Semantic Information G Theory and Logical Bayesian Inference for Machine Learning [PDF]
An important problem with machine learning is that when label number n\u3e2, it is very difficult to construct and optimize a group of learning functions, and we wish that optimized learning functions are still useful when prior distribution P(x) (where ...

Deterministic Annealing Approach to Fuzzy C-Means Clustering Based on Entropy Maximization
This paper is dealing with the fuzzy clustering method which combines the deterministic annealing (DA) approach with an entropy, especially the Shannon entropy and the Tsallis entropy.

Conditional Probabilities and Fuzzy Entropy
Let \((\Omega, S, P)\) be a probability space and \(A \in S\) an event with its indicator function \(1_ A\). It is well-known that the conditional probability with respect to a subfield \(G \subset S\) satisfies \(P(A \mid G) = 1_ A\) if \(A \in G\) and that \(P(A \mid G)\) is a general function on [0,1] if \(A\) is not measurable with respect to \(G\).
