Webon Hierarchical Optimistic Optimization (HOO). The al-gorithm guides the system to improve the choice of the weight vector based on observed rewards. Theoretical anal-ysis of our algorithm shows a sub-linear regret with re-spect to an omniscient genie. Finally through simulations, we show that the algorithm adaptively learns the optimal 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.

Web14 de out. de 2024 · In order to address this problem, we propose a generic extension of hierarchical optimistic tree search (HOO), called ProCrastinated Tree Search (PCTS), that flexibly accommodates a delay and noise-tolerant bandit algorithm. We provide a generic proof technique to quantify regret of PCTS under delayed, noisy, and multi-fidelity … WebThe hierarchical optimization problem [11, 16, 23] conceptually extends the open-loop Stackelberg model to K players.

We provide a regret analysis for LD-HOO and show that, asymptotically, our algorithm exhibits the same cumulative regret as the original HOO … 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 … iration automatic chords
