WebApr 11, 2024 · We study estimation of piecewise smooth signals over a graph. We propose a $\\ell_{2,0}$-norm penalized Graph Trend Filtering (GTF) model to estimate piecewise smooth graph signals that exhibits inhomogeneous levels of smoothness across the nodes. We prove that the proposed GTF model is simultaneously a k-means clustering on the … WebJul 6, 2024 · A principled graph trend collaborative filtering method is introduced and the Graph Trend Filtering Networks for recommendations (GTN) that can capture the adaptive reliability of the interactions is proposed.

Web1.1. Graph Trend Filtering Problem Description Chapter 2 starts with the trend ltering problem, and revisits how graph trend ltering is generalized from the univariate setting. A nice property of graph trend ltering is that the reconstructed signal is piecewise-polynomial, of which the degree depends on the order of the problem.
