JeffBorwey / GraphClustering

GraphClustering is a C# GUI for data mining and clustering research. In particular, this implements the graph based resilience measure Vertex Attack Tolerance (VAT) and the adapted clustering algorithm Hierarchical VAT Clustering (hVATClust). The NetMining library provides many other common clustering algorithms (K-Means, SOM, Girvan-Newman, etc.), Several ADTs (Quadtree, Heap, DisjointSet), Dimensionality Reduction, Data Generation, and Internal(Dunn, Silhouette, Davies–Bouldin) and External Clustering evaluation.

cluster file format #3

Closed taba1345 closed 6 years ago

taba1345 commented 6 years ago

for using cluster validity (internal or external Eval.) the grapphclustering needs a file with *.cluster format. what is the format of this file? how can we make it?

with regards Tabatabaei

JeffBorwey commented 6 years ago

Here is an example clustering of the iris data set

There are 3 sections in a .cluster file Points (absolute or relative path to points file)

Clusters (number of clusters) (length of cluster) (space seperated index list of each cluster item) ... (length of cluster) (space seperated index list of each cluster item)

Meta (any data or comments you want to store along with the cluster file)

Here is an example:

Points iris.txt
