Three different RL algorithms are used to analyse performance: the value func- tion method DQN, the policy gradient method PPO, and the actor-critic method.
A Control Algorithm for Sea?Air Cooperative Observation Tasks ...Q, which updates the value network by gradient descent. Because the target policy is a deterministic strategy, in contrast to the execution. Bachelor's Thesis Implementation and Evaluation of Reinforcement ...Using this function. J(?), one can optimize the policy by maximizing J(?) using optimization methods such as gradient descent. [32, p. 10f.] The main advantages ... Memory-based Deep Reinforcement Learning in Endless Imperfect ...during gradient descent, excessively large optimization steps might be taken, resulting in an oscillating behavior that fails to converge to a local minimum.
