cherab.phix.inversion.lcurve.Lcurve.basis

property Lcurve.basis: ndarray

The inverted solution basis \(\tilde{V} \in \mathbb{R}^{n\times r}\).

If the regularization term is described as \(||Lx||^2\), then \(\tilde{V} = L^{-1}V \in \mathbb{R}^{n\times r}\), where \(V\in\mathbb{R}^{n\times r}\) is the right singular vectors of \(A\) and \(L^{-1}\) is the inverse of regularization operator \(L \in \mathbb{R}^{n\times n}\).
