WebJun 25, 2024 · In this way, the over-smoothing phenomenon is alleviated, while the similarities between the unlabeled features and labeled ones from the same class are enhanced. Experimental results on five popular datasets show that the proposed SelfSAGCN outperforms state-of-the-art methods on various classification tasks. WebOct 10, 2024 · GCN performs optimally when the network level is two layers, beyond which the over smoothing phenomenon occurs. Since GCN continuously aggregates neighboring node features, the global node features tend to be similar after multi-layer network aggregation, while weakening the nodes’ features and producing over smoothing.
