Item Splash in a Flash: Sharpness-aware Minimization for Efficient Liquid Splash Simulation(The Eurographics Association, 2022) Jetly, Vishrut; Ibayashi, Hikaru; Nakano, Aiichiro; Sauvage, Basile; Hasic-Telalovic, JasminkaWe present sharpness-aware minimization (SAM) for fluid dynamics which can efficiently learn the plausible dynamics of liquid splashes. Due to its ability to achieve robust and generalizing solutions, SAM efficiently converges to a parameter set that predicts plausible dynamics of elusive liquid splashes. Our training scheme requires 6 times smaller number of epochs to converge and, 4 times shorter wall-clock time. Our result shows that sharpness of loss function has a close connection to the plausibility of fluid dynamics and suggests further applicability of SAM to machine learning based fluid simulation.
