Witrynaexpressivity is strong, i.e., there exists at least one global minimizer with zero training loss. Second, we identify a nice local region with no local-min or saddle points. Nevertheless, it is not clear whether gradient descent can stay in this nice re-gion. Third, we consider a constrained optimization formulation where the feasible Witryna2 wrz 2024 · Although some methods introduce multi-scale expressivity to improve the features expressivity, the large filter kernel requires considerably more parameters. … WitrynaWe theoretical demonstrate how SHADOW-GNN improves expressivity from three different angles. On SHADOW-GCN (Section 3.1), we come from the graph signal processing perspective. The GCN propagation can be interpreted as applying ﬁltering on the node signals [47].
