A Fast Density-based Clustering Algorithm Using Fuzzy
... and FN-DBSCAN can provide good clustering quality, i.e two clusters can be found and noisy data can be detected. The detailed results of clustering quality with different sizes are shown in Fig. 1(a). We observe that the landmark FN-DBSCAN algorithm and the FN-DBSCAN algorithm achieved similar resul ...

The definitions of distance functions are usually very different for interval-scaled, boolean, categorical, ordinal ratio, and vector variables. Weights should be assoc ...
