Improving the interpretability of GNN predictions through conformal-based graph sparsification

no code implementations18 Apr 2024 Pablo Sanchez-Martin, Kinaan Aamir Khan, Isabel Valera

Graph Neural Networks (GNNs) have achieved state-of-the-art performance in solving graph classification tasks.

Variational Mixture of HyperGenerators for Learning Distributions Over Functions

1 code implementation13 Feb 2023 Batuhan Koyuncu, Pablo Sanchez-Martin, Ignacio Peis, Pablo M. Olmos, Isabel Valera

Recent approaches build on implicit neural representations (INRs) to propose generative models over function spaces.

Learnable Graph Convolutional Attention Networks

1 code implementation21 Nov 2022 Adrián Javaloy, Pablo Sanchez-Martin, Amit Levi, Isabel Valera

Existing Graph Neural Networks (GNNs) compute the message exchange between nodes by either aggregating uniformly (convolving) the features of all the neighboring nodes, or by applying a non-uniform score (attending) to the features.

VACA: Design of Variational Graph Autoencoders for Interventional and Counterfactual Queries

1 code implementation27 Oct 2021 Pablo Sanchez-Martin, Miriam Rateike, Isabel Valera

In this paper, we introduce VACA, a novel class of variational graph autoencoders for causal inference in the absence of hidden confounders, when only observational data and the causal graph are available.
