.cp_to_vec¶

cp_to_vec
(cp_tensor)[source]¶ Turns the khatriproduct of matrices into a vector
(the tensor
factors = [U_1, ... U_n]
is converted into a raveled mode0 unfolding) Parameters
 cp_tensorCPTensor = (weight, factors)
factors is a list of matrices, all with the same number of columns i.e.:
for u in U: u[i].shape == (s_i, R)
where R is fixed while s_i can vary with i
 Returns
 ndarray
vectorised tensor
