If we keep A matrix fixed (3,3) we have to operate a ‘dot’ product with the transpose of B [=> (5,3)] and we get a (3,3) result. In python this is easy with: num=np.dot(A,B.T) Cell Denominator: It ’s a simple multiplication between 2 numbers but first we have to...

@maarten, This is not an issue, but just a question about how to extract the similarity matrix and labels in BERTopic if one wishes to. The only workaround, I could think of, given my limited experience with Python, is the following, but...

MatrixSimilarity.load('/tmp/deerwester.index') This is true for all similarity indexing classes (similarities.Similarity, similarities.MatrixSimilarity and similarities.SparseMatrixSimilarity). Also in the following, index can be an object of any of these. When in doubt, use similarities.Similarity...
