Autonomous clustering using rough set theory [PDF]

open access: yes, 2008
This paper proposes a clustering technique that minimises the need for subjective human intervention and is based on elements of rough set theory. The proposed algorithm is unified in its approach to clustering and makes use of both local and global ...

Population annealing: Theory and application in spin glasses [PDF]

open access: yes, 2015
Population annealing is an efficient sequential Monte Carlo algorithm for simulating equilibrium states of systems with rough free energy landscapes. The theory of population annealing is presented, and systematic and statistical errors are discussed ...

Electromagnetic Scattering and Statistic Analysis of Clutter from Oil Contaminated Sea Surface [PDF]

open access: yes, 2015
In order to investigate the electromagnetic (EM) scattering characteristics of the three dimensional sea surface contaminated by oil, a rigorous numerical method multilevel fast multipole algorithm (MLFMA) is developed to preciously calculate the ...

Martingale approximations and anisotropic Banach spaces with an application to the time-one map of a Lorentz gas [PDF]

open access: yes, 2020
In this paper, we show how the Gordin martingale approximation method fits into the anisotropic Banach space framework. In particular, for the time-one map of a finite horizon planar periodic Lorentz gas, we prove that Holder observables satisfy ...

Rough statistical convergence in neutrosophic normed spaces

open access: yesAnnals of Communications in Mathematics, 2023
Neutrosophic normed spaces, one of the recent hot issues in mathematics, are covered in this paper. The Neutrosophic approach is based on the idea that the degree of uncertainty should be taken into consideration and that it is insufficient to categorise problems in daily life as either right or wrong.

A Novel Function Mining Algorithm Based on Attribute Reduction and Improved Gene Expression Programming

open access: yesIEEE Access, 2019
It is very interesting and important to determine the function model for remote-sensing data. The existing statistical and artificial intelligence models still have some defects.

A Hybrid Probabilistic-Neutrosophic Adaptive Convergence Model for Analyzing Innovative Performance of Agricultural Technology Enterprises in the Digital Economy [PDF]

open access: yesNeutrosophic Sets and Systems
This paper introduces a novel mathematical framework that integrates hybrid probabilistic-neutrosophic logic with adaptive rough ideal statistical convergence (AR-I st) to model and analyze the dynamic performance of innovative agricultural technology ...

Ballistic Localization in Quasi-1D Waveguides with Rough Surfaces

open access: yes, 2003
Structure of eigenstates in a periodic quasi-1D waveguide with a rough surface is studied both analytically and numerically. We have found a large number of "regular" eigenstates for any high energy.

Pathwise stability of likelihood estimators for diffusions via rough paths

open access: yes, 2016
We consider the classical estimation problem of an unknown drift parameter within classes of nondegenerate diffusion processes. Using rough path theory (in the sense of T.

Interactions within the turbulent boundary layer at high Reynolds number [PDF]

open access: yes, 2011
Simultaneous streamwise velocity measurements across the vertical direction obtained in the atmospheric surface layer (Re_τ ≃ 5 × 10^5) under near thermally neutral conditions are used to outline and quantify interactions between the scales of turbulence,
