We argue that implicit representations, in particular signed distance functions (SDFs), provide a smooth, richly informative representation of local object geometry, useful not just for statics but for …

Tīmeklis2024. gada 10. marts · Yet even though neural network models see increasing use in the physical sciences, they struggle to learn these symmetries. In this paper, we propose Lagrangian Neural Networks (LNNs), which can parameterize arbitrary Lagrangians using neural networks. In contrast to models that learn Hamiltonians, LNNs do not … TīmeklisIn physics, Lagrangian mechanics is a formulation of classical mechanics founded on the stationary-action principle (also known as the principle of least action). It was …
