Basis builder through \(\mathcal{L}^2\) regression
Given a map \(M\), fit a supplied parametric transport map \(T\) through the solution of the \(\mathcal{L}^2\) regression problem
\[\arg\min_{\bf a}\left\Vert M - T \right\Vert_{\mathcal{L}^2} + \alpha \Vert {\bf a} \Vert_x\]where \(\alpha\Vert{\bf a}\Vert_x\) is a regularization term, with respect to one of the available norms.
- Parameters:
regression_params (dict) – dictionary of regression parameters
