The multiple subset sum problem is an optimization problem in computer science and operations research. It is a generalization of the subset sum problem. The input to the problem is a multiset of n integers and a positive integer m representing the number of subsets. The goal is to construct, from the input integers, some m subsets. The problem ...
Consensus clustering is a method of aggregating (potentially conflicting) results from multiple clustering algorithms.Also called cluster ensembles [1] or aggregation of clustering (or partitions), it refers to the situation in which a number of different (input) clusterings have been obtained for a particular dataset and it is desired to find a single (consensus) clustering which is a better ...
Graph-based model s: a clique, that is, a subset of nodes in a graph such that every two nodes in the subset are connected by an edge can be considered as a prototypical form of cluster. Relaxations of the complete connectivity requirement (a fraction of the edges can be missing) are known as quasi-cliques, as in the HCS clustering algorithm .
Claude-Ambroise Seurat (10 April 1797 [1] or 4 April 1798 [2] – after 1833 [2]) was a freak show attraction from Troyes, France. He was known as "the anatomical man or the living skeleton" ( French : l'homme anatomique ou le squelette vivant ) due to his extraordinarily low body weight.
The average silhouette of the data is another useful criterion for assessing the natural number of clusters. The silhouette of a data instance is a measure of how closely it is matched to data within its cluster and how loosely it is matched to data of the neighboring cluster, i.e., the cluster whose average distance from the datum is lowest.

A sequence enumerating all positive rational numbers.Each positive real number is a cluster point.. Let be a subset of a topological space. A point in is a limit point or cluster point or accumulation point of the set if every neighbourhood of contains at least one point of different from itself.
The subset sum problem (SSP) is a decision problem in computer science. In its most general formulation, there is a multiset of integers and a target-sum , and the question is to decide whether any subset of the integers sum to precisely . [1] The problem is known to be NP-complete.
Human genetic clusters tend to be organized by geographic ancestry, with divisions between clusters aligning largely with geographic barriers such as oceans or mountain ranges. [2] [3] Clustering studies have been applied to global populations, [4] as well as to population subsets like post-colonial North America.
