WebThe work [37] seems to be the rst work where the graph-based semi-supervised learn-ing was introduced. The authors of [37] formulated the semi-supervised learning method as a constrained optimization problem involving graph Laplacian. Then, in [35, 36] the authors proposed optimization formulations based on several variations of the graph ... Web2 Graph Laplacian Regularization The graph Laplacian is well known for its usefulness in spectral clustering [29], among many other appli-cations. In the remote sensing field, it has been used by [21] to convert a hyperspectral image to RGB for better visualization. Assuming the unknown SRI is aligned spatially with the MSI, we exploit the ...
Web– In graph learning, a graph Laplacian regularization is employed to promote simplicity of the learned graph – In (ill-posed) inverse problems, a regularization term is sometimes used to ensure some type of unique solution. – In algorithms, regularization is used to make operations more stable. (Cf. Gauss-Newton vs. Levenberg-Marquardt)
