Multi-point Feedback of Bandit Convex Optimization with Hard Constraints

no code implementations17 Oct 2023 Yasunari Hikima

We also extend the result for the case where the loss functions are strongly convex and show that both regret and constraint violation bounds can be further reduced.

Bézier Flow: a Surface-wise Gradient Descent Method for Multi-objective Optimization

no code implementations23 May 2022 Akiyoshi Sannai, Yasunari Hikima, Ken Kobayashi, Akinori Tanaka, Naoki Hamada

In this paper, we propose a strategy to construct a multi-objective optimization algorithm from a single-objective optimization algorithm by using the B\'ezier simplex model.
