WebDynamic treatment regimes are treatment allocations tailored to heterogeneous in-dividuals. The optimal dynamic treatment regime is a regime that maximizes counter … WebA dynamic treatment regime (DTR) is a sequence of decision rules that adapt to the time-varying states of an individual. Black-box learning methods have shown great potential in predicting the optimal treatments; however, the resulting DTRs lack interpretability, which is of paramount importance for medical experts to understand and implement.
