CVDD
An Internal Validity Index Based on Density-Involved Distance
https://ieeexplore.ieee.org/document/8672850
Requirement
The source code is written by Matlab r2016a. Versions lower than Matlab r2012a have not been tested.
Simplest Demo
-
RUN Ncut_test.m to determine the optimal partition from varied partitions (produced by Jianbo Shi's Normalized cuts).
CVDD.m
includes Algorithm 1: CVDD in our paper.Ncut_test.m
as an example includes Algorithm 2: CVDD-OP in our paper.'OP_CA' (in
Ncut_test.m
) shows the comparison. [ Purity, CVDD, CVNN, WB, Silhouette, CH, DB, Dunn, S_Dbw, I ]
Parameters in CVDD
No need to tune.
Datasets used
File Datasets_all30
includes 10 non-spherical clusters, 10 spherical clusters and 10 classification datasets (real datasets) used in the experiments of our paper.
