Graph Context Encoder: Graph Feature Inpainting for Graph Generation and Self-supervised Pretraining

no code implementations18 Jun 2021 Oriel Frigo, Rémy Brossard, David Dehaene

We propose the Graph Context Encoder (GCE), a simple but efficient approach for graph representation learning based on graph feature masking and reconstruction.

Graph convolutions that can finally model local structure

1 code implementation30 Nov 2020 Rémy Brossard, Oriel Frigo, David Dehaene

Despite quick progress in the last few years, recent studies have shown that modern graph neural networks can still fail at very simple tasks, like detecting small cycles.

Iterative energy-based projection on a normal data manifold for anomaly localization

1 code implementation ICLR 2020 David Dehaene, Oriel Frigo, Sébastien Combrexelle, Pierre Eline

Indeed, an autoencoder trained on normal data is expected to only be able to reconstruct normal features of the data, allowing the segmentation of anomalous pixels in an image via a simple comparison between the image and its autoencoder reconstruction.
