DenMune: Density peak based clustering using mutual nearest neighbors

作者:

Highlights:

• We present a novel algorithm (pseudo code given) to find clusters of arbitrary number, shapes and densities in two-dimensions. Higher dimensions are first reduced to 2-D using the t-sne algorithm.

• The algorithm relies on a single parameter K (the number of nearest neighbors).

• The algorithm proposes a simple rule that classifies the data points into three types: those that certainly belong to clusters/ certainly do not belong to any cluster (i.e. noise) and uncertain points (that either succeed to join a cluster or are considered, also, as noise).

• The performance of the proposed algorithm is compared to nine well known algorithms using  thirty-six real and synthetic data sets.

• The results show the superiority of the proposed algorithm.
