How would I make clusters from a Levenshtein similarity matrix?

I have a similarity matrix of words and would like to apply an algorithm that can put the words in clusters. Here’s the example I have so far: Obviously this is a very simple dummy example, but what I would expect the output to be is 2 clusters, one with ‘The Bachelor’,’The Bachelorette’,’The Bachelor Special’, and the other with ‘SportsCenter’,’SportsCenter

What’s the fastest way in Python to calculate cosine similarity given sparse matrix data?

Given a sparse matrix listing, what’s the best way to calculate the cosine similarity between each of the columns (or rows) in the matrix? I would rather not iterate n-choose-two times. Say the input matrix is: The sparse representation is: In Python, it’s straightforward to work with the matrix-input format: Gives: That’s fine for a full-matrix input, but I really
