CUR Decomposition
Project description
CUR Decomposition
CUR Decomposition as described in Mining of Massive Datasets, page 406.
Currently it only works with Numpy arrays but the point of CUR is to keep C and R sparse if M is sparse so I plan to add support for Scipy Sparse arrays.
Usage
M = np.array([ ... ])
r = int
from cur import cur_decomposition
C, U, R = cur_decomposition(M, r)
