Clustering matrix
WebConnectivity matrix. Defines for each feature the neighboring features following a given structure of the data. This can be a connectivity matrix itself or a callable that transforms the data into a connectivity matrix, such as derived from kneighbors_graph. Default is None, i.e, the hierarchical clustering algorithm is unstructured. WebSimply convert each matrix into a vector of 128*19 length, and concatenate your "matrix vectors" into one huge matrix, which you can cluster as usual. edit. One important note …
