WebNov 13, 2005 · Farthest- First [4,5] clustering algorithm that combines hierarchi- cal clustering and distance-based clustering. In particular, uses the basic idea of agglomerative hierarchical... In computational geometry, the farthest-first traversal of a compact metric space is a sequence of points in the space, where the first point is selected arbitrarily and each successive point is as far as possible from the set of previously-selected points. The same concept can also be applied to a finite set of geometric … See more A farthest-first traversal is a sequence of points in a compact metric space, with each point appearing at most once. If the space is finite, each point appears exactly once, and the traversal is a permutation of all of the points in … See more Rosenkrantz, Stearns & Lewis (1977) used the farthest-first traversal to define the farthest-insertion heuristic for the travelling salesman problem. This heuristic finds approximate solutions to the travelling salesman problem by building up a tour on a subset … See more • Lloyd's algorithm, a different method for generating evenly spaced points in geometric spaces See more Greedy exact algorithm The farthest-first traversal of a finite point set may be computed by a greedy algorithm that maintains the distance of each point from the previously selected points, performing the following steps: • Initialize … See more
WebThe problem description in this proposed methodology, referred to as attribute-related cluster sequence analysis, is to identify a good working algorithm for clustering of protein structures by comparing four existing algorithms: k-means, expectation maximization, farthest first and COB.
