Large scale paired antibody language models

no code implementations26 Mar 2024 Henry Kenlay, Frédéric A. Dreyer, Aleksandr Kovaltsuk, Dom Miketa, Douglas Pires, Charlotte M. Deane

Antibodies are proteins produced by the immune system that can identify and neutralise a wide variety of antigens with high specificity and affinity, and constitute the most successful class of biotherapeutics.

Structure-Aware Robustness Certificates for Graph Classification

1 code implementation20 Jun 2023 Pierre Osselin, Henry Kenlay, Xiaowen Dong

Certifying the robustness of a graph-based machine learning model poses a critical challenge for safety.

Graph Classification

Graph similarity learning for change-point detection in dynamic networks

no code implementations29 Mar 2022 Deborah Sulem, Henry Kenlay, Mihai Cucuringu, Xiaowen Dong

The main novelty of our method is to use a siamese graph neural network architecture for learning a data-driven graph similarity function, which allows to effectively compare the current graph and its recent history.

Adversarial Attacks on Graph Classifiers via Bayesian Optimisation

1 code implementation NeurIPS 2021 Xingchen Wan, Henry Kenlay, Robin Ru, Arno Blaas, Michael Osborne, Xiaowen Dong

While the majority of the literature focuses on such vulnerability in node-level classification tasks, little effort has been dedicated to analysing adversarial attacks on graph-level classification, an important problem with numerous real-life applications such as biochemistry and social network analysis.

On the Unreasonable Effectiveness of Feature propagation in Learning on Graphs with Missing Node Features

1 code implementation23 Nov 2021 Emanuele Rossi, Henry Kenlay, Maria I. Gorinova, Benjamin Paul Chamberlain, Xiaowen Dong, Michael Bronstein

While Graph Neural Networks (GNNs) have recently become the de facto standard for modeling relational data, they impose a strong assumption on the availability of the node or edge features of the graph.

Adversarial Attacks on Graph Classification via Bayesian Optimisation

1 code implementation4 Nov 2021 Xingchen Wan, Henry Kenlay, Binxin Ru, Arno Blaas, Michael A. Osborne, Xiaowen Dong

While the majority of the literature focuses on such vulnerability in node-level classification tasks, little effort has been dedicated to analysing adversarial attacks on graph-level classification, an important problem with numerous real-life applications such as biochemistry and social network analysis.

Interpretable Stability Bounds for Spectral Graph Filters

no code implementations18 Feb 2021 Henry Kenlay, Dorina Thanou, Xiaowen Dong

In this paper, we study filter stability and provide a novel and interpretable upper bound on the change of filter output, where the bound is expressed in terms of the endpoint degrees of the deleted and newly added edges, as well as the spatial proximity of those edges.

On the Stability of Graph Convolutional Neural Networks under Edge Rewiring

no code implementations ICLR Workshop GTRL 2021 Henry Kenlay, Dorina Thanou, Xiaowen Dong

Graph neural networks are experiencing a surge of popularity within the machine learning community due to their ability to adapt to non-Euclidean domains and instil inductive biases.
