Double Equivariance for Inductive Link Prediction for Both New Nodes and New Relation Types

1 code implementation2 Feb 2023 Jianfei Gao, Yangze Zhou, Jincheng Zhou, Bruno Ribeiro

We then show how double-equivariant architectures are able to self-supervise pre-train on distinct KG domains and zero-shot predict links on a new KG domain (with completely new entities and new relation types).

Bias Challenges in Counterfactual Data Augmentation

no code implementations12 Sep 2022 S Chandra Mouli, Yangze Zhou, Bruno Ribeiro

Deep learning models tend not to be out-of-distribution robust primarily due to their reliance on spurious features to solve the task.

OOD Link Prediction Generalization Capabilities of Message-Passing GNNs in Larger Test Graphs

1 code implementation30 May 2022 Yangze Zhou, Gitta Kutyniok, Bruno Ribeiro

This work provides the first theoretical study on the ability of graph Message Passing Neural Networks (gMPNNs) -- such as Graph Neural Networks (GNNs) -- to perform inductive out-of-distribution (OOD) link prediction tasks, where deployment (test) graph sizes are larger than training graphs.

Size-Invariant Graph Representations for Graph Classification Extrapolations

1 code implementation8 Mar 2021 Beatrice Bevilacqua, Yangze Zhou, Bruno Ribeiro

In general, graph representation learning methods assume that the train and test data come from the same distribution.
