CURE (Clustering Using REpresentatives) is an efficient data clustering algorithm for large databases[citation needed]. (wikipedia.org)
The popular K-means clustering algorithm minimizes the sum of squared errors criterion: E = ∑ i = 1 k ∑ p ∈ C i ( p − m i ) 2 , {\displaystyle E=\sum _{i=1}^{k}\sum _{p\in C_{i}}(p-m_{i})^{2},} Given large differences in sizes or geometries of different clusters, the square error method could split the large clusters to minimize the square error, which is not always correct. (wikipedia.org)
The problem with the BIRCH algorithm is that once the clusters are generated after step 3, it uses centroids of the clusters and assigns each data point to the cluster with the closest centroid. (wikipedia.org)
To avoid the problems with non-uniform sized or shaped clusters, CURE employs a hierarchical clustering algorithm that adopts a middle ground between the centroid based and all point extremes. (wikipedia.org)
The clusters with the closest pair of representatives are the clusters that are merged at each step of CURE's hierarchical clustering algorithm. (wikipedia.org)

Here we show how known sources of spike count variability affect stimulus-evoked spike time patterns between neurons separated over multiple layers and columns of adult rat somatosensory cortex in vivo. (nature.com)
On subsets of trials (clusters) and after controlling for stimulus-response adaptation, spike time differences between pairs of neurons are "time-warped" (compressed/stretched) by trial-to-trial changes in shared excitability, explaining why fixed spike time patterns and noise correlations are seldom reported.
