Clustering - is the task of discovering groups and structures in the data that are in one way or another 'similar.' In case of spectrum sensing, this could be that a group of sensing devices are shadowed by a common obstacle.
These analysts are tasked with processing large quantities of information and forming associations for a variety of reasons including but not limited to knowledge discovery, discovering groups and individual of interest, and analyzing criminal or terrorist networks.
Measuring coherence with the objective of discovering groups of neurons that act together in a coherent fashion (i.e., Hebbian cell assemblies) (Hebb 1949), has a long history (Horwitz 2003).
Dr. Ronald Kahn, director of the Joslin Diabetes Center in Boston, said this research would focus more attention on a recently discovered group of enzymes called sirtuins that resveratrol is believed to affect.
This relatively newly discovered group of bacteria includes strictly anaerobic, chemo-organotrophic, fermentative bacteria (Denger et al. 2002).
Interferon (IFN -λ1 [also known as IFN -λ1ukin (IL)-29] belongs to the recently discovered group of type III IFNs.
Saccharophagus degradans belongs to a recently discovered group of marine bacteria equipped with an arsenal of sugar cleaving enzymes coupled to carbohydrate-binding domains to degrade various insoluble complex polysaccharides.
But a newly discovered group of these microorganisms forgoes this photosynthesis and, in doing so, becomes a nitrogen-rich natural fertilizer for the oceans, according to research published today in Science (p. 1110).
The more recently discovered group was given the name Entoprocta, while the original "Bryozoa" were called "Ectoprocta".
