Minimum spanning tree hierarchical clustering algorithm: A new Pythagorean fuzzy similarity measure for the analysis of functional brain networks

作者:

Highlights:

• The paper tackles the situations where network parameters may be uncertain.

• We let the network parameters to take the form of Pythagorean fuzzy (PF) numbers.

• We propose a graph theory-based agglomerative hierarchical clustering technique.

• A minimum spanning tree agglomerative hierarchical clustering method is used.

• A functional brain network is used to prove its practicality and efficiency.
