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.
