Hierarchical optimistic optimization
Web2. In Section 3 we describe the basic strategy proposed, called HOO (hierarchical optimistic optimization). 3. We present the main results in Section 4. We start by specifying and explaining our as-sumptions (Section 4.1) under which various regret … WebFirst, we study a gradient-based bi-level optimization method for learning tasks with convex lower level. In particular, by formulating bi-level models from the optimistic viewpoint and aggregating hierarchical objective information, we establish Bi-level Descent Aggregation (BDA), a flexible and modularized algorithmic framework for bi-level programming.

Web11 de jul. de 2014 · Many of the standard optimization algorithms focus on optimizing a single, scalar feedback signal. However, real-life optimization problems often require a simultaneous optimization of more than one objective. In this paper, we propose a multi-objective extension to the standard χ-armed bandit problem. As the feedback signal is …
