Silhouette (clustering)
If the cluster centers are medoids (as in k-medoids clustering) instead of arithmetic means (as in k-means clustering), this is also called the medoid-based Silhouette Clustering Instead of using the average silhouette to evaluate a clustering obtained from, e.g., k-medoids or k-means, we can try to directly wikipedia.org

Key clustering
Key or hash function should avoid clustering, the mapping of two or more keys to consecutive slots. Such clustering may cause the lookup cost to skyrocket, even if the load factor is low and collisions are infrequent. wikipedia.org

A question about stability of clustering I'm reading a paper about interactive clustering, and I'm stuck with a definition about stability property of a clustering (based on this paper): !enter image description here...
It means that the similarity between any subset $A$ of any cluster $C_i$ and the remaining nodes of $C_i$ should be greater than the similarity between $A$ and any subset $A'$ of any other cluster $C_j$. Basically, the author mean that **intra** -cluster similarity should be greater than **inter** -...

Different between k-center and max diameter clustering Consider the clustering problem: **Given a set of points, partition them into $k$ clusters such that the maximum diameter of all the clusters gets minimized.** Th...
These two clustering rules do not necessarily produce the same results Suppose you have the following four points and you want $k=2$ clusters: * $A

High clustering coefficient and large average path length in one graph Can somebody provide an example of a network with a high clustering coefficient and a large average path length? A visual representation of such a...
You could think of a graph with a number of big clumps of complete graph, then the clumps are connected by long chains. Most vertices will be in a clump, but the average distance will be dominated by the long distance between the clumps.

Complete-linkage clustering - Wikipedia
Complete-linkage clustering is one of several methods of agglomerative hierarchical clustering. At the beginning of the process, each element is in a cluster of its own. The clusters are then sequentially combined into larger clusters until all elements end up being in the same cluster.

In a scale-free network, how does the global clustering coefficient scales with the number of nodes? The title pretty much says it all. I have a directed graph with $n$ nodes such that the distribution of degrees foll...
According to this paper the global clustering coefficient for a scale-free graph declines at rate $n^{-\frac{\left(\alpha-2\right)^2}{2\alpha}}$ where

clustering #. clustering. #. clustering(G, nodes=None, weight=None) [source] #. Compute the clustering coefficient for nodes. For unweighted graphs, the clustering of a node u is the fraction of possible triangles through that node that exist, c u = 2 T ( u) d e g ( u) ( d e g ( u) − 1), where T ( u) is the number of triangles through node u ...

Is the laplacian L derived from the affinity matrix A in spectral clustering always block diagonal? I am currently working through the theory of spectral clustering and most of the 'tutorials' explain the laplacian L ...
It is block diagonal in the sense that you can always permute vertices such that each block represents a maximal cluster. Note that the eigenvalues will not change because if your original matrix is $L$, and you permute it to be block diagonal, you get $\tilde{L}=P^TLP$, where $P$ is your permutatio...
