intra-cluster and inter-cluster distances

Hello

I have a question about the intra-cluster and inter-cluster distances

i find many formula and so i have a trouble

the intra-cluster distance is measured as the mean of the distance between data and the centroid of their clusters? the inter-cluster distance is the min distance between all the centroids of the clusters?

please help me

Hi Nadjoua,

Certainly,

• Intra-cluster distance is typically the average distance of all points in a cluster to the cluster's centroid.
• Inter-cluster distance is often measured as the distance between the centroids of two clusters, although the minimum distance between any pair of points from two different clusters is also used.

These metrics help assess the compactness of clusters and the separation between them, respectively.

I hope it helps!
