Files:
Wrapper.py - basic wrapper to run the test the DDC algorithm on 2D data and plot the results.
DDC_01.py - DDC algorithm implementation including the basic algorithm, a simple merge function and visualizations options.
gaussian5000.csv - data file containg 5 random clusters of gaussian distributed data of 5000+ samples for cluster. This is the type of data distributions best suited to DDC.
DS2.csv - standard test dataset of arbitrarily shaped data groups. Although DDC will created correct, pure clusters this data shows the limitations of DDC in working with non-standard data distrbutions. (To work with this type of data, see DDCAS, Data Density based Clustering for Arbitrary Shapes.)
