E(3)-equivariant models cannot learn chirality: Field-based molecular generation

ICLR 2025poster

Obtaining the desired effect of drugs is highly dependent on their molecular geometries. Thus, the current prevailing paradigm focuses on 3D point-cloud atom representations, utilizing graph neural network (GNN) parametrizations, with rotational symmetries baked in via E(3) invariant layers. We prov…

Learning Spatiotemporal Dynamical Systems from Point Process Observations

ICLR 2025spotlight

Spatiotemporal dynamics models are fundamental for various domains, from heat propagation in materials to oceanic and atmospheric flows. However, currently available neural network-based spatiotemporal modeling approaches fall short when faced with data that is collected randomly over time and space…

Latent Neural ODEs with Sparse Bayesian Multiple Shooting

ICLR 2023poster

Training dynamic models, such as neural ODEs, on long trajectories is a hard problem that requires using various tricks, such as trajectory splitting, to make model training work in practice. These methods are often heuristics with poor theoretical justifications, and require iterative manual tuning…

Learning Space-Time Continuous Latent Neural PDEs from Partially Observed States

NeurIPS 2023poster

We introduce a novel grid-independent model for learning partial differential equations (PDEs) from noisy and partial observations on irregular spatiotemporal grids. We propose a space-time continuous latent neural PDE model with an efficient probabilistic framework and a novel encoder design for im…

Learning continuous-time PDEs from sparse data with graph neural networks

ICLR 2021poster

The behavior of many dynamical systems follow complex, yet still unknown partial differential equations (PDEs). While several machine learning methods have been proposed to learn PDEs directly from data, previous methods are limited to discrete-time approximations or make the limiting assumption of…
