An end-to-end (E2E) reinforcement learning model for autonomous vehicle collision avoidance in the CARLA simulator, using a recurrent PPO algorithm for dynamic control. The model processes RGB camera inputs to make real-time acceleration and steering decisions. machine-learning reinforcement-learning ...
A sample of 7653 women of black and white races who had two pregnancies during the study period were examined to determine if a relationship existed between the recurrence of PPO and a recurrence of placental pathology.;Analysis used several statistical techniques including linear logistic regression ...

Actor是Agent的行为模块,它负责执行动作。在Actor-Critic算法中,Actor通常是一个随机的策略网络,它根据当前的状态选择一个动作。具体的算法步骤如下: 初始化Actor网络的参数。 初始化Target网络的参数。 初始化优化器。 初始化经验回放存储器。 初始化训练循环。

The high-risk patient had no abnormality in the electrocardiogram and the echocardiography in spite of having a history of coronary vasospastic angina; however, both %ppo-FEV1 and %ppo-DLco were slightly less than 40% (38.0 and 37.8%, respectively) in the pulmonary function test. Because ...
One of the advantages of PPO is that it directly learns the policy, rather than indirectly via the values (the way Q Learning uses Q-values to learn the policy). It can work well in continuous action spaces, which is suitable in our use case and can learn (through mean and standard ...
