DBSCAN: could also be an option, but I want all nodes/strings to belong to a cluster and not be considered "noise. Storing and updating matrices of 'affinities', 'responsibilities' and 'similarities' between samples can be memory-intensive. It assigns the datapoints to the clusters iteratively by shifting points towards the highest density of datapoints. 3. However I'm surprised that the Affinity Propagation (AP) method has been here suggested just to find the number of cluster for the k-means method, where in general AP do a better job clustering the data.

A brief description for the algorithm of affinity propagation is as follow. These are the clustering algorithms I've been looking into: Affinity propagation: : seems like a good solution, but the memory usage seems way too high, since the data is dense. And he explains the technicalities in a simple and understandable way. It looks at the “mode” of the density, and where it is highest, and will iteratively shift points in the plot towards the closest mode – resulting in a number of clusters, and the ability to assign a sample to a cluster, after fitting is complete (ML | mean-shift clustering, 2019). Spectral clustering. Clustering of unlabeled data can be performed with the module sklearn.cluster..
