What are Clusters in High Dimensions and are they Difficult to Find?,low-dimensional data set. Concentration of norm is one of the phenomena from which high-dimensional data sets can suffer. It means that in high dimensions – under certain general assumptions – the relative distances from any point to its closest and farthest neighbour tend to be almost identical.

A Rough Fuzzy Perspective to Dimensionality Reduction,ny real–world problems. The focus of rough set theory is on the ambiguity caused by limited discernibility of objects in the domain of discourse; granules are formed as objects and are drawn together by the limited discernibility among them.

Data Dimensionality Estimation: Achievements and Challanges,al submanifold. Since the value of M is unknown, techniques that allow knowing in advance the value of M, called intrinsic dimension (ID), are quite useful. The aim of the paper is to make the state-of-art of the methods of intrinsic dimensionality estimation, underlining the achievements and the challanges.作者: 一條卷發(fā) 時間: 2025-3-27 09:16 作者: guardianship 時間: 2025-3-27 09:31

Efficient Density-Based Subspace Clustering in High Dimensions,ibutes in such high-dimensional spaces. As the number of possible subsets is exponential in the number of attributes, efficient algorithms are crucial. This short survey discusses challenges in this area, and presents models and algorithms for efficient and scalable density-based subspace clustering.作者: Dysplasia 時間: 2025-3-28 18:39 作者: exophthalmos 時間: 2025-3-28 18:47 作者: TRAWL 時間: 2025-3-29 02:51
A Rough Fuzzy Perspective to Dimensionality Reduction, helps to exploit, at the same time, properties like coarseness and vagueness. We describe a model of the hybridization of rough and fuzzy sets, that allows for further refinements of rough fuzzy sets and show its application to the task of unsupervised feature selection.作者: Emmenagogue 時間: 2025-3-29 06:41
