WebOf course, it is also worth noting that your quote says (emphasis mine): The target policy $\pi$ [...] may be deterministic [...]. It says that $\pi$ may be deterministic (and in practice it very often is, because we very often take $\pi$ to be the greedy policy)... but sometimes it won't be. The entire approach using the importance sampling ratio is well-defined also for … Webarbitrary target policy π, given that all data is generated by a different behavior policy b, where b is soft, meaning b (s; a) > 0 8 s 2 S a A. 3. Importance Sampling Algorithms One way of viewing the special difficulty of off-policy learning is that it is a mismatch of distributions—we would

For such target policies, the only cases where the importance-sampled return will be non-zero is when the behavior policy follows a trajectory that exactly matches one that the target ... statistics about writing down goals

So, it is possible that in the target policy, we could have state values (or state action values) coming from different trajectories. If the above is true, and if the values depend on the subsequent actions (the behavior policy), there ... WebJan 25, 2024 · The best way to target policies for unregistered devices is by using the negative operator since the configured filter rule would apply. If you were to use a positive operator, the filter rule would only apply when a device exists in the directory and the configured rule matches the attribute on the device. ...
