Benchmarking Large Language Models for Molecule Prediction Tasks

1 code implementation8 Mar 2024 Zhiqiang Zhong, Kuangyu Zhou, Davide Mottin

Our investigation reveals several key insights: Firstly, LLMs generally lag behind ML models in achieving competitive performance on molecule tasks, particularly when compared to models adept at capturing the geometric structure of molecules, highlighting the constrained ability of LLMs to comprehend graph data.

On the Robustness of Post-hoc GNN Explainers to Label Noise

no code implementations4 Sep 2023 Zhiqiang Zhong, Yangqianzi Jiang, Davide Mottin

Proposed as a solution to the inherent black-box limitations of graph neural networks (GNNs), post-hoc GNN explainers aim to provide precise and insightful explanations of the behaviours exhibited by trained GNNs.

How Faithful are Self-Explainable GNNs?

no code implementations29 Aug 2023 Marc Christiansen, Lea Villadsen, Zhiqiang Zhong, Stefano Teso, Davide Mottin

Self-explainable deep neural networks are a recent class of models that can output ante-hoc local explanations that are faithful to the model's reasoning, and as such represent a step forward toward filling the gap between expressiveness and interpretability.

"Double vaccinated, 5G boosted!": Learning Attitudes towards COVID-19 Vaccination from Social Media

no code implementations27 Jun 2022 Ninghan Chen, Xihui Chen, Zhiqiang Zhong, Jun Pang

To address the vaccine hesitancy which impairs the efforts of the COVID-19 vaccination campaign, it is imperative to understand public vaccination attitudes and timely grasp their changes.

Simplifying Node Classification on Heterophilous Graphs with Compatible Label Propagation

1 code implementation19 May 2022 Zhiqiang Zhong, Sergey Ivanov, Jun Pang

Graph Neural Networks (GNNs) have been predominant for graph learning tasks; however, recent studies showed that a well-known graph algorithm, Label Propagation (LP), combined with a shallow neural network can achieve comparable performance to GNNs in semi-supervised node classification on graphs with high homophily.
