Recent advances in data-driven approaches have shown impressive results in prediction and control of dynamical systems. In particular, deep neural networks provide accurate predictions and superhuman performance in some application domains. However, pure data-driven methods generally require a huge amount of data, and the learned models often have limited generalizability. These issues restrict the applicability of pure data-driven methods in many real world dynamical systems where data collection is expensive and generalization is critical. Model-based approaches aim to solve the sample-efficiency and generalization challenges by constructing models to utilize prior knowledge. In this talk, I will share the idea of combining data-driven and analytical models to improve generalization and online adaptation in predicting physical interactions. I will also discuss model-based reinforcement learning methods and new approaches to improve sample efficiency and performance in dynamical environments.
