在现实生活中,存在着大量语言值数据.为了解决在语言环境中不确定信息的聚类问题,本文提出了一种新的机器学习方法,即基于核方法的模糊对象语言概念格聚类分析模型.该模型通过融合层次聚类与概念格聚类的原理,在寻找到层次聚类局部最优层次的同时优化概念格聚类中的概念选择与概念构造问题.具体地,提出模糊对象语言概念格及其相关性质,它的外延与内涵分别用模糊集与语言术语集来描述,不仅可以表达模糊信息和语言值信息,而且可以描述不同群体之间的语言信息差异;分别分析层次聚类与模糊对象语言概念格聚类,在此基础上,结合核方法计算模糊对象语言概念格中样本间的相似程度,构造基于层次聚类方法的模糊对象语言概念格聚类分析模型;实验结果表明,该模型是有效的,可以集成层次聚类与概念格聚类的优势.

In this paper a gauge theory is proposed for the two-band model of Chem insulators.Based on the so-called \'t Hooft monopole model,a U(1) Maxwell electromagnetic sub-field is constructed from an SU(2) gauge field,from which arise two types of topologica
By imposing the boundary condition associated with the boundary structure of the null boundaries rather than the usual one,we find for Einstein\'s gravity that the variational principle works only in its submanifold with the null boundaries given by the
The spectrum of hadronic molecules composed of heavy-antiheavy charmed hadrons has been obtained in our previous work.The potentials are constants at the leading order,which are estimated from resonance saturation.The experimental candidates of hadronic m
Out-of-time-ordered correlation(OTOC)functions have been used as an indicator of quantum chaos in a lot of physical systems.In this work,we numerically demonstrate that zero temperature OTOC can detect quantum phase transition in the anisotropic Dicke mod
Many physical systems can be successfully modelled using equations that admit the soliton solutions.In addition,equations with soliton solutions have a significant mathematical structure.In this paper,we study and analyze a three-dimensional soliton equat
We discuss a general interaction quench in a Luttinger liquid described by a paired bosonic Hamiltonian.By employing su(1,1) Lie algebra,the post-quench time-evolved wavefunctions are obtained analytically,from which the time evolution of the entanglement
Self-consistency in nonextensive statistical mechanics is studied as a recourse to parameter transformation,where different nonextensive parameters are presented for various theoretical branches.The unification between the first and third choices of the a
In this work we consider black hole solutions to Einstein\'s theory coupled to a nonlinear power-law electromagnetic field with a fixed exponent value.We study the extended phase space thermodynamics in canonical and grand canonical ensembles,where the
From the perspective of Markovian piecewise deterministic processes(PDPs),we investigate the derivation of a kinetic uncertainty relation(KUR),which was originally proposed in Markovian open quantum systems.First,stationary distributions of classical PDPs
