WebMar 12, 2024 · In this article, we will look at the Trust Region Policy Optimization (TRPO) algorithm, a direct policy-based method for finding the optimal behavior in Reinforcement … In mathematical optimization, a trust region is the subset of the region of the objective function that is approximated using a model function (often a quadratic). If an adequate model of the objective function is found within the trust region, then the region is expanded; conversely, if the approximation is poor, then the region is contracted. The fit is evaluated by comparing the ratio of expected improvement from the model approximat…
