To formulate and solve the estimation of optimal individualized treatment rules for patients with heterogeneous responses as an outcome-weighted classification problem.
Reformulated optimal treatment rule estimation into a weighted classification framework where individual weights correspond to clinical outcomes.
Developed an outcome weighted learning approach utilizing the support vector machine framework.
Derived consistency proofs and finite sample risk bounds, followed by validation through simulations and chronic depression trial data.
Demonstrated theoretical consistency for the estimated individualized treatment rule estimator.
Established a finite sample bound limiting the difference between expected clinical outcomes under the estimated rule versus the true optimal rule.
Showed superior decision accuracy qualitatively in simulation scenarios and real-world chronic depression data compared to traditional methods.
