WebAnalogous to the univariate case, graph trend filtering exhibits a level of local adaptivity unmatched by the usual \ell_2-based graph smoothers. It is also defined by a convex minimization problem that is readily solved (e.g., by fast ADMM or Newton algorithms). We demonstrate the merits of graph trend filtering through examples and theory.
