Clustering of clusters

Pattern Recognition, 1992
Abstract An algorithm for the clustering of existing clusters is introduced in this paper. The algorithm was adopted from fuzzy-c-mean and modifications made to take into account the extra information, i.e. some data samples already form clusters. Partition coefficients, together with some other criteria, are used for testing cluster validity.

Reorganization of clusters in cluster-cluster-aggregation

AIP Conference Proceedings, 2000
X-ray microscopy and scattering experiments give different experimental results when determining the fractal dimension of colloidal clusters. A two dimensional simulation model is presented to describe reorganization of clusters during the aggregation process. Considering this reorganization gives a rapidly increasing fractal dimension from d=1.53 to d=

When is a cluster not a cluster?

Clinical Linguistics & Phonetics, 2001
L'A. presente les resultats d'une etude visant a evaluer, dans le cadre de l'acquisition du langage, la these de J. Archibald (1998) selon laquelle la presence d'un ensemble constitue d'une consonne et d'une liquide implique la presence d'un contraste sous-jacent entre /l/ et /r/. Ceci permet certaines predictions concernant les liquides et les types d'

Clustering and Clusters [PDF]

open access: possible, 1978
When one is lecturing in a centre for interdisciplinary research, it is, I imagine, appropriate to start by emphasizing the interdisciplinary character of the topic one is going to discuss. In my case this does not present any difficulty. Clustering is a pictorial term for positive correlations in an ensemble of randomly distributed bodies or events ...

To Cluster or Not to Cluster

Science's STKE, 2007
The PDZ domain is a frequently occurring interaction domain in eukaryotic proteins that binds to the C termini of target proteins. PDZ domains have been thought to cluster into functional classes, each with distinct sequence binding preferences. Using a combination of experimental data and modeling, Stiffler et al .

Clustering and Clusters

2009
In this chapter, we shall show several spatial point patterns in a hypothetical area of a square 10 km on each side to understand what “clustering” or “a cluster” means and to get a basic idea of how to approach detection of clustering or clusters.
