It extremely affects not only the clustering quality but also the efficiency of the algorithm. However, the traditional linkage methods do not consider the effect of the objects around cluster centers. Based on this motivation, in this article, we propose a novel linkage method, named k-centroid...
Z = linkage(X,method,metric) performs clustering by passing metric to the pdist function, which computes the distance between the rows of X. example Z = linkage(X,method,metric,'savememory',value) uses a memory-saving algorithm when value is 'on', and uses the standard algorithm when valu...

Unlike other methods, the average linkage method has better performance on ball-shaped clusters in the feature space. In general, the performance of an agglomerative hierarchical clustering method often suffers from its inability to adjust, once a merge decision has been executed. The same is true...
The results show that the proposed approach can often produce more accurate clustering results, when compared with the traditional linkage methods in terms of accuracy rate.

The difference between the various hierarchical- linkage methods depends on how they define "closest" when comparing groups. For single-linkage clustering, the closest two groups are determined by the closest observations be- tween the two groups. In complete linkage, the closest two groups are ...

The'centroid'and'median'methods can produce a cluster tree that is not monotonic. This result occurs when the distance from the union of two clusters,rands, to a third cluster is less than the distance betweenrands. In this case, in a dendrogram drawn with the default orientation, the path...
We discuss these results in the context of where GBS is likely to be most useful in sugarcane crop development. Methods Mapping population and DNA extraction The mapping population consisted of 151 full sibs de- rived from a commercial cross between the SP80-3280 (female parent) and RB835486...
functions and methods for their application to particular problems in machine learning and data mining. We begin by introducing two learnable similarity functions for strings. The first one is based on a probabilistic model of edit distance with affine gaps (Gotoh, 1982), a widely used chara...
