WebMar 8, 2024 · It is shown that a simple soft-max approximation to the optimal treatment regime, for an appropriately fast growing temperature parameter, can achieve valid inference on the truly optimal regime. Estimating optimal dynamic policies from offline data is a fundamental problem in dynamic decision making. In the context of causal inference, the … WebA dynamic treatment regime consists of a sequence of decision rules, one per stage of intervention, that dictate how to individualize treatments to patients based on evolving treatment and covariate history. These regimes are particularly useful for managing chronic disorders, and fit well into the larger paradigm of personalized medicine.

WebApr 25, 2003 · The ascertainment of optimal dynamic treatment regimes belongs to the class of sequential or multistage decision problems. We consider dynamic treatment regimes in which decisions are to be made at set times; in this case the regime is a set of decision rules, with one rule per time interval.
