New internal index for clustering validation based on graphs

作者:

Highlights:

• Minimum spanning tree graph-based clustering is applied.

• The concept ``cohesion" is introduced to measure the clusters quality and distance.

• A new internal validation index that captures the geometry of cluster is defined.

• It has been proved effective on 16 datasets of different shapes and sizes.

• The two versions of the new index show better performance than traditional ones.
