Winners of PCQM4Mv2 Track (Leaderboard)

1st place: WeLoveGraphs (contact)
  • Team members: Dominic Masters (Graphcore), Kerstin Klaser (Graphcore), Josef Dean (Graphcore), Hatem Helal (Graphcore), Adam Sanders (Graphcore), Sam Maddrell-Mander (Graphcore), Zhiyi Li (Graphcore), Deniz Beker (Graphcore), Dominique Beaini (Valence Discovery/Universite de Montreal/Mila Quebec), Ladislav Rampasek (Universite de Montreal/Mila Quebec)
  • Method: GPS++ (112 model ensemble)
  • Short summary: We use GPS++, a hybrid message passing neural network (MPNN) and transformer that builds on the General, Powerful, Scalable (GPS) framework presented by Rampášek et al. [2022]. Specifically, this combines a large and expressive message passing module with a biased self-attention layer to maximise the benefit of local inductive biases while still allowing for effective global communication. Furthermore, we integrate a grouped input masking method to exploit available 3D positional information and use a denoising loss to alleviate oversmoothing.

  • Method: 20 Transformer-M-ViSNet + 2 Pretrained-3D-ViSNet
  • Short summary: We designed two kinds of models: Transformer-M-ViSNet which is a geometry-enhanced graph neural network for fully connected molecular graphs and Pretrained-3D-ViSNet which is a pretrained ViSNet by distilling geometric information from optimized structures. 22 models with different settings are ensembles.

  • Method: Heterogenous Ensemble of Models
  • Short summary: Our method combines variants of the recent TransformerM architecture with Transformer, GNN, and ResNet backbone architectures. Models are trained on the 2D data, 3D data, and image modalities of molecular graphs. We ensemble these models with a HuberRegressor. The models are trained on 4 different train/validation splits of the original train + valid datasets.
