Gradual model generator for single-pass clustering - Karkkainen, Franti - 2005 () Citation Context ...sampling [22, 26] have been proposed but for large data sets even a representative sample may be big enough so that it does not fit in memory. Recently, many single pass algorithms have...

According to Jain׳s definition, “The goal of data clustering, also known as cluster analysis, is to discover the natural grouping(s) of a set of patterns, points, or objects” [5]. Data clustering has various applications in different fields. For example, in Computer Vision, Image ...
Due to recent advances in technology, online clustering has emerged as a challenging and interesting problem, with applications such as peer-to-peer information retrieval, and topic detection and tracking. Single-pass clustering is particularly one of the popular methods used in this field. While...
Most of them address the crisp case of clustering, which cannot be easily generalized to the fuzzy case. In this paper, we propose a simple single pass (through the data) fuzzy c means algorithm that neither uses any complicated data structure nor any complicated data compression techniques, ...

Single-pass clustering,中文名一般译作“单遍聚类”,它是一种简洁且高效的文本聚类算法。在文本主题聚类中,Single-pass聚类算法比K-means来的更为有效。Single-pass聚类算法不需要指定类目数量,可以通过设定相似度阈值来限定聚类数量。 Single-pass聚类算法同时是一种增量聚类算法(Incremental Clustering Algorithm),每个...
Though standard deviations of these parameters overlap for different protein categories, the observed trend in changes of average values provides additional support for the clustering of bitopic proteins into three distinct groups. 3.7.
