WebApr 17, 2024 · We study the problem of jointly estimating several network processes that are driven by the same input, recasting it as one of blind identification of a bank of graph filters. More precisely, we consider the observation of several graph signals - i.e., signals defined on the nodes of a graph - and we model each of these signals as the output of a … WebApr 25, 2016 · The blind graph-filter identification problem can thus be tackled via rank and sparsity minimization subject to linear constraints, an inverse problem amenable to …
