Reliable forecasts of the Earth system are crucial for human progress and safety from natural disasters.
EvDNeRF: Reconstructing Event Data with Dynamic Neural Radiance Fields
We present EvDNeRF, a pipeline for generating event data and training an event-based dynamic NeRF, for the purpose of faithfully reconstructing eventstreams on scenes with rigid and non-rigid deformations that may be too fast to capture with a standard camera.

Learning Modular Simulations for Homogeneous Systems
We evaluate our framework on a variety of systems and show that message passing allows coordination between multiple modules over time for accurate predictions and in certain cases, enables zero-shot generalization to new system configurations.
Towards Multi-spatiotemporal-scale Generalized PDE Modeling
Finally, we show promising results on generalization to different PDE parameters and time-scales with a single surrogate model.
Learning to Simulate Realistic LiDARs
Simulating realistic sensors is a challenging part in data generation for autonomous systems, often involving carefully handcrafted sensor design, scene properties, and physics modeling.
Clifford Neural Layers for PDE Modeling
We empirically evaluate the benefit of Clifford neural layers by replacing convolution and Fourier operations in common neural PDE surrogates by their Clifford counterparts on 2D Navier-Stokes and weather modeling tasks, as well as 3D Maxwell equations.

Training Structured Mechanical Models by Minimizing Discrete Euler-Lagrange Residual
Structured Mechanical Models (SMMs) are a data-efficient black-box parameterization of mechanical systems, typically fit to data by minimizing the error between predicted and observed accelerations or next states.
Scalable Anytime Planning for Multi-Agent MDPs
We also introduce a multi-drone delivery domain with dynamic, i. e., state-dependent coordination graphs, and demonstrate how our approach scales to large problems on this domain that are intractable for other MCTS methods.
Scalable Identification of Partially Observed Systems with Certainty-Equivalent EM
System identification is a key step for model-based control, estimator design, and output prediction.

We consider the problem of dynamically allocating tasks to multiple agents under time window constraints and task completion uncertainty.
Structured Mechanical Models for Robot Learning and Control
Deep neural networks have been used to learn models of robot dynamics from data, but they suffer from data-inefficiency and the difficulty to incorporate prior knowledge.

Learning interpretable and transferable subpolicies and performing task decomposition from a single, complex task is difficult.
A General Framework for Structured Learning of Mechanical Systems
We address the need for a flexible, gray-box model of mechanical systems that can seamlessly incorporate prior knowledge where it is available, and train expressive function approximators where it is not.
