AdaSelection: Accelerating Deep Learning Training through Data Subsampling

no code implementations19 Jun 2023 Minghe Zhang, Chaosheng Dong, Jinmiao Fu, Tianchen Zhou, Jia Liang, Jia Liu, Bo Liu, Michinari Momma, Bryan Wang, Yan Gao, Yi Sun

In this paper, we introduce AdaSelection, an adaptive sub-sampling method to identify the most informative sub-samples within each minibatch to speed up the training of large-scale deep learning models without sacrificing model performance.

SLPerf: a Unified Framework for Benchmarking Split Learning

1 code implementation4 Apr 2023 Tianchen Zhou, Zhanyi Hu, Bingzhe Wu, Cen Chen

Data privacy concerns has made centralized training of data, which is scattered across silos, infeasible, leading to the need for collaborative learning frameworks.

Incentivized Bandit Learning with Self-Reinforcing User Preferences

no code implementations19 May 2021 Tianchen Zhou, Jia Liu, Chaosheng Dong, Jingyuan Deng

In this paper, we investigate a new multi-armed bandit (MAB) online learning model that considers real-world phenomena in many recommender systems: (i) the learning agent cannot pull the arms by itself and thus has to offer rewards to users to incentivize arm-pulling indirectly; and (ii) if users with specific arm preferences are well rewarded, they induce a "self-reinforcing" effect in the sense that they will attract more users of similar arm preferences.
