Finding the number of clusters in a dataset: An information-theoretic approach
… For the datasets of Figures 1(b) and 1(c), our jump method correctly chooses K¤ D G D 6
and K¤ D G D 1. For the iris data, it indicates that either two or three clusters is a reasonable …

Clustering for sparsely sampled functional data
We develop a flexible model-based procedure for clustering functional data. The technique
can be applied to all types of curve data but is particularly useful when individuals are …

Are clupeid microphagists herbivorous or omnivorous? A review of the diets of some commercially important clupeids
AG James - South African Journal of Marine Science, 1988 - Taylor & Francis
There are two main schools of thought regarding the diet of clupeids, especially those
inhabiting upwelling regions: either that they are herbivorous or that they are omnivorous but …
