For the purpose of DBSCAN clustering, the points are classified as core points, (directly-) reachable points and outliers, as follows: A point p is a core point if at least minPts points are within distance ε of it (including p). A point q is directly reachable from p if point q is within distance ε from core point p. Points are only said to ...
English: Illustration of en:DBSCAN cluster analysis (minPts=3). Points around A are core points. Points B and C are not core points, but are density-connected via the cluster of A (and thus belong to this cluster). Point N is Noise, since it is neither a core point nor reachable from a core point.
A cluster in DBSCAN is only guaranteed to consists of at least 1 core point. Since border points that belong to more than 1 cluster will be "randomly" (usually: first-come) assigned to one of the clusters, a core point may not be able to retain/get all its neighbors. Thus, it may be smaller than minPts. One dimensional example: minPts=4, epsilon=1:
A point p is a core point if at least MinPts points are found within its ε-neighborhood () (including point p itself). In contrast to DBSCAN , OPTICS also considers points that are part of a more densely packed cluster, so each point is assigned a core distance that describes the distance to the MinPts th closest point:

urban street sport involving climbing and leaping, using buildings, walls, curbs to ricochet off much as if one were on a skateboard, often in follow-the-leader style. Originally a phonetic form of the French word parcours, which means "a run, a route" Also known as, or the predecessor to, "free running", developed by Sébastien Foucan. parole
Clustering high-dimensional data is the cluster analysis of data with anywhere from a few dozen to many thousands of dimensions.Such high-dimensional spaces of data are often encountered in areas such as medicine, where DNA microarray technology can produce many measurements at once, and the clustering of text documents, where, if a word-frequency vector is used, the number of dimensions ...
A rendition of the Vauquois triangle, illustrating the various approaches to the design of machine translation systems.. The direct, transfer-based machine translation and interlingual machine translation methods of machine translation all belong to RBMT but differ in the depth of analysis of the source language and the extent to which they attempt to reach a language-independent ...
