From Latent Graph to Latent Topology Inference: Differentiable Cell Complex Module

no code implementations25 May 2023 Claudio Battiloro, Indro Spinelli, Lev Telyatnikov, Michael Bronstein, Simone Scardapane, Paolo Di Lorenzo

Latent Graph Inference (LGI) relaxed the reliance of Graph Neural Networks (GNNs) on a given graph topology by dynamically learning it.

Combining Stochastic Explainers and Subgraph Neural Networks can Increase Expressivity and Interpretability

no code implementations14 Apr 2023 Indro Spinelli, Michele Guerra, Filippo Maria Bianchi, Simone Scardapane

Subgraph-enhanced graph neural networks (SGNN) can increase the expressive power of the standard message-passing framework.

Explainability in subgraphs-enhanced Graph Neural Networks

1 code implementation16 Sep 2022 Michele Guerra, Indro Spinelli, Simone Scardapane, Filippo Maria Bianchi

Recently, subgraphs-enhanced Graph Neural Networks (SGNNs) have been introduced to enhance the expressive power of Graph Neural Networks (GNNs), which was proved to be not higher than the 1-dimensional Weisfeiler-Leman isomorphism test.

A Meta-Learning Approach for Training Explainable Graph Neural Networks

1 code implementation20 Sep 2021 Indro Spinelli, Simone Scardapane, Aurelio Uncini

Experiments on synthetic and real-world datasets for node and graph classification show that we can produce models that are consistently easier to explain by different algorithms.

FairDrop: Biased Edge Dropout for Enhancing Fairness in Graph Representation Learning

no code implementations29 Apr 2021 Indro Spinelli, Simone Scardapane, Amir Hussain, Aurelio Uncini

Furthermore, to better evaluate the gains, we propose a new dyadic group definition to measure the bias of a link prediction task when paired with group-based fairness metrics.

Distributed Training of Graph Convolutional Networks

no code implementations13 Jul 2020 Simone Scardapane, Indro Spinelli, Paolo Di Lorenzo

After formulating the centralized GCN training problem, we first show how to make inference in a distributed scenario where the underlying data graph is split among different agents.

Adaptive Propagation Graph Convolutional Network

1 code implementation24 Feb 2020 Indro Spinelli, Simone Scardapane, Aurelio Uncini

Graph convolutional networks (GCNs) are a family of neural network models that perform inference on graph data by interleaving vertex-wise operations and message-passing exchanges across nodes.

Efficient data augmentation using graph imputation neural networks

no code implementations20 Jun 2019 Indro Spinelli, Simone Scardapane, Michele Scarpiniti, Aurelio Uncini

Recently, data augmentation in the semi-supervised regime, where unlabeled data vastly outnumbers labeled data, has received a considerable attention.

Missing Data Imputation with Adversarially-trained Graph Convolutional Networks

1 code implementation6 May 2019 Indro Spinelli, Simone Scardapane, Aurelio Uncini

We also explore a few extensions to the basic architecture involving the use of residual connections between layers, and of global statistics computed from the data set to improve the accuracy.
