WebSep 26, 2024 · This decay is partly attributed to oversmoothing, where repeated graph convolutions eventually make node embeddings indistinguishable. We take a closer look at two different interpretations, aiming to quantify oversmoothing. Our main contribution is PairNorm, a novel normalization layer that is based on a careful analysis of the graph ... WebThese observations motivate us to tackle the over-smoothing issue by mitigating the early over-smoothing in the local regions. A straightforward method is to follow the practice of DropEdge [11], that is, reducing the connectivity of hub regions by randomly dropping out a portion of edges during training.However, like the canonical dropout [16], randomly …
WebMany articles online say GNNs suffer from over-smoothing because nodes aggregate their neighbors and many nodes share similar sets of neighbors. However, in CNN, each pixel also aggregates its neighbors. But CNN can still perform well on some pixel-level classification tasks such as segmentation.
