Reasoning in Visual Navigation of End-to-end Trained Agents: A Dynamical Systems Approach

CVPR 2025highlight

Progress in Embodied AI has made it possible for end-to-end-trained agents to navigate in photo-realistic environments with high-level reasoning and zero-shot or language-conditioned behavior, but evaluations and benchmarks are still dominated by simulation. In this work, we focus on the fine-graine…

Space and time continuous physics simulation from partial observations

ICLR 2024spotlight

Modern techniques for physical simulations rely on numerical schemes and mesh-refinement methods to address trade-offs between precision and complexity, but these handcrafted solutions are tedious and require high computational power. Data-driven methods based on large-scale machine learning promise…

EAGLE: Large-scale Learning of Turbulent Fluid Dynamics with Mesh Transformers

ICLR 2023poster

Estimating fluid dynamics is classically done through the simulation and integration of numerical models solving the Navier-Stokes equations, which is computationally complex and time-consuming even on high-end hardware. This is a notoriously hard problem to solve, which has recently been addressed…

Filtered-CoPhy: Unsupervised Learning of Counterfactual Physics in Pixel Space

ICLR 2022oral

Learning causal relationships in high-dimensional data (images, videos) is a hard task, as they are often defined on low dimensional manifolds and must be extracted from complex signals dominated by appearance, lighting, textures and also spurious correlations in the data. We present a method for le…
