Thorough pre-employment screening is undertaken during the recruitment process. Detailed scripts and training will be available. The Contact Tracer will make outbound calls to those individuals who have tested positive for COVID19 and identify anyone that has been in contact with them prior to infection and will provide advice on self-isolation. This service is provided on a remote working basis with all roles being homebased. The Contract Tracing service operates 7 days a week, 8am to 8pm and is key to slowing the spread of COVID-19 and keeping our local community a safe place to live and work. As part of the Gwent Regional response Blaenau Gwent County Borough Council are currently recruiting a number of critical positions to join our Contact Tracing Team. It will undertake effective and extensive contact tracing, and support people to self-isolate where required to do so.

However, in the case where a stochastic policy is preferred, such guarantees are no longer held. It is worth noting that Proposition 2 only says that by mixing on- and off-policy data, it is possible for V-trace to learn an optimal greedy policy. if \(\pi\) visits state \(x\) more often than \(\mu\). Less on-policy data is required if \(d^\mu(x)\over d^\pi(x)\) is small, i.e. That is, when \(Q^\omega\) has the same optimal action as \(Q\), the proportion of on-policy data does not matter. At last, we demonstrate that it is possible for V-trace to learn a local optimal greedy policy from off-policy data if we mix in a proportion of on-policy data. In this post, we theoretically analyze V-trace, showing that when data is way off-policy, V-trace does not converge to a local optimal solution, not even when an optimal value function is provided. 2018, targets at near-on-policy data and has been successfully applied to solving challenging tasks such as StarCraft II.
