WebThis repo will contain PyTorch implementation of various fundamental RL algorithms. It's aimed at making it easy to start playing and learning about RL. The problem I came across investigating other DQN projects is that they either: Don't have any evidence that they've actually achieved the published results Web深度学习中的优化算法采用的原理是梯度下降法，选取适当的初值params，不断迭代，进行目标函数的极小化，直到收敛。由于负梯度方向时使函数值下降最快的方向，在迭代的每一步，以负梯度方向更新params的值，从而达到减少函数值的目的。

Web3-5 RMSprop算法. RMSprop 和 Adadelta 一样，也是对 Adagrad 的一种改进。 RMSprop 采用均方根作为分 母，可缓解 Adagrad 学习率下降较快的问题， 并且引入均方根，可以减少摆动。 torch.optim.RMSprop(params, lr=0.01, alpha=0.99, eps=1e-08, weight_decay=0, momentum=0, centered=False) Webclass RMSprop ( Optimizer ): def __init__ ( self, params, lr=1e-2, alpha=0.99, eps=1e-8, weight_decay=0, momentum=0, centered=False, foreach: Optional [ bool] = None, maximize: bool = False, differentiable: bool = False, ): if not 0.0 <= lr: raise ValueError ( "Invalid learning rate: {}". format ( lr )) if not 0.0 <= eps: phentermine 37.5 reviews and testimonials
