There are a lot of clusters that DBSCAN can discover which are unable to find by using KMeans clustering algorithm. But, DBSCAN does not work well when we deal with clusters of varying densities and high dimensional data. It is sensitive to clustering parameters like MinPts and Eps values. ...

Every data mining task has the problem of parameters. Every parameter influences the algorithm in sepcifc ways. For DBSCAN the parameters epsilon and MinPnts are needed. The parameters must be specified by the user of the algorithms since other data sets and other questions require differnt param...

idx = dbscan(X,epsilon,minpts) partitions observations in the n-by-p data matrix X into clusters using the DBSCAN algorithm (see Algorithms). dbscan clusters the observations (or points) based on a threshold for a neighborhood search radius epsilon and a minimum number of neighbors minpts requi...
