ADAPT: Zero-Shot Adaptive Policy Transfer for Stochastic Dynamical Systems James Harrison1, Animesh Garg2, Boris Ivanovic2, Yuke Zhu2, Silvio Savarese2, Li Fei-Fei2, Marco Pavone3 Abstract Model-free policy learning has enabled good performance on complex tasks that were previously intractable with traditional control techniques. While model-free deep reinforcement learning algorithms are capable of learning a wide range of robotic skills, they typically suffer from very high sample complexity. DRL for continuous control (especially actor-critic framework) has advan-tages of both immediate control and predictive control.

After deriving the model predictive path integral control (MPPI) algorithm, we compare it with an existing model predictive control formulation based on differential dynamic programming (DDP) [13 – 15]. Self-learning (or self-play in the context of games)= Solving a DP problem using simulation-based policy iteration. We use model-predictive control (MPC; Richards,2005) to allow the agent to adapt its plan based on new observations, meaning we replan at each step. Classical model-based control methods, which include sampling- and lattice-based algorithms and model predictive control, suffer from the trade-off between model complexity and computational burden required for the online solution of expensive optimization or search problems at every short sampling time. However, the sample complexity of model-free algorithms, particularly when using high-dimensional function approximators, tends to limit their applicability to physical systems. For example, the rolling horizon optimization or model predictive control (MPC) is one of the most popular model-based approaches. Model-based reinforcement learning (RL) algorithms can attain excellent sample efficiency, but often lag behind the best model-free algorithms in terms of asymptotic performance, especially those with high-capacity parametric function approximators, such as deep networks.

In this project, deep neural networks and convolutional neural networks were been used to clone driving behavior. After deriving the model predictive path integral control (MPPI) algorithm, we compare it with an existing model predictive control formulation based on differential dynamic programming (DDP) [13 – 15].

Request PDF on ResearchGate | Extending Deep Model Predictive Control with Safety Augmented Value Estimation from Demonstrations | Reinforcement learning (RL) for robotics is challenging due to. Unlike locomotion,. ¿Por qué es importante usar MATLAB y Simulink? El 82 % de las empresas de la lista Fortune 100 utilizan MATLAB, lo que significa que usted podrá aplicar sus ideas fuera del aula para impulsar las nuevas tecnologías y progresar en su carrera profesional. Deep Learning Toolbox Model Predictive Control Toolbox Articles on reinforcement learning, humanoid robot control, battery performance optimization, range. At each decision step the agent observes the state of the system, and based on this observation it chooses. We perfomed a large number of experiments tweaking architectures and hyperparameters, but the final results was often for the algorithm to constantly increase the gains.
