Age of Computing: A Metric of Computation Freshness in Communication and Computation Cooperative Networks

no code implementations8 Mar 2024 Xingran Chen, Yusha Liu, Yali Zheng, Kun Yang

In this letter, we introduce the novel concept, Age of Computing (AoC), to capture computation freshness in 3CNs.

Adaptation to Misspecified Kernel Regularity in Kernelised Bandits

no code implementations26 Apr 2023 Yusha Liu, Aarti Singh

In continuum-armed bandit problems where the underlying function resides in a reproducing kernel Hilbert space (RKHS), namely, the kernelised bandit problems, an important open problem remains of how well learning algorithms can adapt if the regularity of the associated kernel function is unknown.

Integrating Rankings into Quantized Scores in Peer Review

1 code implementation5 Apr 2022 Yusha Liu, Yichong Xu, Nihar B. Shah, Aarti Singh

Our approach addresses the two aforementioned challenges by: (i) ensuring that rankings are incorporated into the updates scores in the same manner for all papers, thereby mitigating arbitrariness, and (ii) allowing to seamlessly use existing interfaces and workflows designed for scores.

Smooth Bandit Optimization: Generalization to Hölder Space

no code implementations11 Dec 2020 Yusha Liu, Yining Wang, Aarti Singh

We also study adaptation to unknown function smoothness over a continuous scale of H\"older spaces indexed by $\alpha$, with a bandit model selection approach applied with our proposed two-layer algorithms.
