Abstract: The processing of signals on graph edges is challenging considering that Graph Signal Processing techniques are defined only on the graph nodes. Leveraging the Line Graph to transform a graph edge signal onto the node of its edge-to-vertex dual, we propose the Line Graph Least Mean Square (LGLMS) algorithm for online time-varying graph edge signal prediction. By setting up an $l_2$-norm optimization problem, LGLMS forms an adaptive algorithm as the graph edge analogy of the …
