Physics-informed Dyna-style model-based deep reinforcement learning for dynamic control; Abstract. This paper proposes a novel machine learning based approach, that formulates physics-based fluid simulation as a regression problem, estimating the acceleration of every particle for each frame, and designed a feature vector, directly modelling individual forces and constraints from the Navier-Stokes equations. A particular emphasis lies on simulating fluid flows, but we are interested in all kinds of PDE-based models.

Abstract: Physics-based and data-driven models for remaining useful lifetime (RUL) prediction typically suffer from two major challenges that limit their applicability to complex real-world domains: (1) incompleteness of physics-based models and (2) limited representativeness of the training dataset for data-driven models.
