WebGenerally, COO is easiest to work with if you are writing human-readable code ;) and will almost always be faster if you have a super-sparse matrix. CSR (Or CSC depending on your linear algebra package/implementation) is generally faster - meaning for a random sparse matrix. There are other more specialized forms of compression that can do ... WebThe predicted regression value of an input sample is computed as the weighted median prediction of the regressors in the ensemble. Parameters: X{array-like, sparse matrix} of shape (n_samples, n_features) The training input samples. Sparse matrix can be CSC, CSR, COO, DOK, or LIL.
