Efficient Frameworks for Generalized Low-Rank Matrix Bandit Problems

no code implementations14 Jan 2024 Yue Kang, Cho-Jui Hsieh, Thomas C. M. Lee

In the stochastic contextual low-rank matrix bandit problem, the expected reward of an action is given by the inner product between the action's feature matrix and some fixed, but initially unknown $d_1$ by $d_2$ matrix $\Theta^*$ with rank $r \ll \{d_1, d_2\}$, and an agent sequentially takes actions based on past experience to maximize the cumulative reward.

Online Continuous Hyperparameter Optimization for Generalized Linear Contextual Bandits

no code implementations18 Feb 2023 Yue Kang, Cho-Jui Hsieh, Thomas C. M. Lee

In stochastic contextual bandits, an agent sequentially makes actions from a time-dependent action set based on past experience to minimize the cumulative regret.

Rethinking Adam: A Twofold Exponential Moving Average Approach

1 code implementation22 Jun 2021 Yizhou Wang, Yue Kang, Can Qin, Huan Wang, Yi Xu, Yulun Zhang, Yun Fu

The intuition is that gradient with momentum contains more accurate directional information and therefore its second moment estimation is a more favorable option for learning rate scaling than that of the raw gradient.

Syndicated Bandits: A Framework for Auto Tuning Hyper-parameters in Contextual Bandit Algorithms

no code implementations5 Jun 2021 Qin Ding, Yue Kang, Yi-Wei Liu, Thomas C. M. Lee, Cho-Jui Hsieh, James Sharpnack

To tackle this problem, we first propose a two-layer bandit structure for auto tuning the exploration parameter and further generalize it to the Syndicated Bandits framework which can learn multiple hyper-parameters dynamically in contextual bandit environment.

Sequence-based deep learning antibody design for in silico antibody affinity maturation

no code implementations21 Feb 2021 Yue Kang, Dawei Leng, Jinjiang Guo, Lurong Pan

Traditional in vitro approaches use hybridoma or phage display for candidate selection, and surface plasmon resonance (SPR) for evaluation, while in silico computational approaches aim to reduce the high cost and improve efficiency by incorporating mathematical algorithms and computational processing power in the design process.
