Detailed Description

template<typename ValueType, elem::Distribution VD>
class skylark::algorithms::regression_solver_t< regression_problem_t< elem::DistMatrix< ValueType, VD, elem::STAR >, linear_tag, l2_tag, no_reg_tag >, elem::DistMatrix< ValueType, VD, elem::STAR >, elem::DistMatrix< ValueType, elem::STAR, elem::STAR >, qr_l2_solver_tag >

Regression solver for L2 linear regrssion on a dense distributed [VC/VR, STAR] matrix. This implementation uses a QR based approach.

A regression solver accepts a right-hand side and output a solution the the regression problem.

The regression problem is fixed, so it is a parameter of the function constructing the regressoion.
