TRPO的objective中包含了重要性采样来补偿training data distribution 和真实的policy state distribution 之间的差距,也就是 \begin{aligned} J(\theta) &=\sum_{s \in S} \rho_{\pi_{\theta_{\text {old}}}(s) \sum_{a \in A} \pi_{\theta_{\text {old}}}(a \mid s) \frac{\pi_{\theta...
behavior policy 是指与environment互动生成training data的策略,target policy 是指你用training data不断去更新、优化,最终要拿去用的那个策略。为什么要搞出这两个概念?其实对于 on-policy 的算法来说,这两样根本就是一个东西!也就是说,我们用于生成training data的behavior policy,在生成了一条training data之后,...
与环境交互的agent和学习的agent是不同的agent shortcoming:on-policy方法,在每次做gradient ascent需要重新sample training data。 off-policy方法与环境交互的agent参数 是固定的,sample的training data可以多次使用。 Import sampling 从概率分布p中sample , 期望为 在不能对p直接采样的情况下,有 因此,我们对概率分布...

The entropy regularization weight is a hyperparameter that should be determined before training. In this paper, 𝛽β was chosen to be equal to 0.0010.001. The differences between DQN and A2C are: The DQN model is an off-policy method, and the A2C model is an on-policy method, i.e.,...

Health workforce planning is based on estimates of future needs for and supply of health care services. Given the pipeline time lag for the training of health professionals, inappropriate workforce planning or policies can lead to extended periods of over- or under-supply of health care providers....
Continuing education and on-the-job training in public health has suffered serious neglect over the past years. As a result, many state and local public health entities have failed to keep step with emerging challenges facing the public's health--challenges that require new and innovative approach...
