Role of Structural and Conformational Diversity for Machine Learning Potentials

no code implementations30 Oct 2023 Nikhil Shenoy, Prudencio Tossou, Emmanuel Noutahi, Hadrien Mary, Dominique Beaini, Jiarui Ding

In the field of Machine Learning Interatomic Potentials (MLIPs), understanding the intricate relationship between data biases, specifically conformational and structural diversity, and model generalization is critical in improving the quality of Quantum Mechanics (QM) data generation efforts.

Gotta be SAFE: A New Framework for Molecular Design

1 code implementation16 Oct 2023 Emmanuel Noutahi, Cristian Gabellini, Michael Craig, Jonathan S. C Lim, Prudencio Tossou

Traditional molecular string representations, such as SMILES, often pose challenges for AI-driven molecular design due to their non-sequential depiction of molecular substructures.

Rethinking Graph Transformers with Spectral Attention

1 code implementation NeurIPS 2021 Devin Kreuzer, Dominique Beaini, William L. Hamilton, Vincent Létourneau, Prudencio Tossou

Here, we present the $\textit{Spectral Attention Network}$ (SAN), which uses a learned positional encoding (LPE) that can take advantage of the full Laplacian spectrum to learn the position of each node in a given graph.

Geodesics in fibered latent spaces: A geometric approach to learning correspondences between conditions

1 code implementation16 May 2020 Tariq Daouda, Reda Chhaibi, Prudencio Tossou, Alexandra-Chloé Villani

This work introduces a geometric framework and a novel network architecture for creating correspondences between samples of different conditions.

MODELLING BIOLOGICAL ASSAYS WITH ADAPTIVE DEEP KERNEL LEARNING

no code implementations25 Sep 2019 Prudencio Tossou, Basile Dura, Daniel Cohen, Mario Marchand, François Laviolette, Alexandre Lacoste

Due to the significant costs of data generation, many prediction tasks within drug discovery are by nature few-shot regression (FSR) problems, including accurate modelling of biological assays.
