Aiming at the existing problems that the selection of neighborhood radius parameter Eps depends on manual experiment, judgment intervention or calculation estimation, the accuracy of clustering results is sensitive to Eps value, using uniform global parameters in non-uniform density data sets makes the ...
DBScan as a high-quality algorithm has been introduced for clustering spatial data due to its ability to remove noise (outlier) and constructing arbitrarily shapes. However, it has a problem in determining a suitable value of Eps parameter. This paper proposes a new cluster...
