The basic idea behind the density-based clustering approach is derived from a human intuitive clustering method. For instance, by looking at the figure below, one can easily identify four clusters along with several points of noise, because of the differences in the density of points. ...
A new density based clustering algorithmECRDBSCANbased onDBSCAN, has been presented in this paper. Computational geometry is applied to develop the modifiedDBSCANalgorithm. It is well known that the quality of density based clustering depends on its input parameters. However, it is not easy to ...
