Personalized Tucker Decomposition: Modeling Commonality and Peculiarity on Tensor Data

no code implementations7 Sep 2023 Jiuyun Hu, Naichen Shi, Raed Al Kontar, Hao Yan

We propose personalized Tucker decomposition (perTucker) to address the limitations of traditional tensor decomposition methods in capturing heterogeneity across different datasets.

Adam Can Converge Without Any Modification On Update Rules

no code implementations20 Aug 2022 Yushun Zhang, Congliang Chen, Naichen Shi, Ruoyu Sun, Zhi-Quan Luo

We point out there is a mismatch between the settings of theory and practice: Reddi et al. 2018 pick the problem after picking the hyperparameters of Adam, i. e., $(\beta_1, \beta_2)$; while practical applications often fix the problem first and then tune $(\beta_1, \beta_2)$.

Fed-ensemble: Improving Generalization through Model Ensembling in Federated Learning

1 code implementation21 Jul 2021 Naichen Shi, Fan Lai, Raed Al Kontar, Mosharaf Chowdhury

In this paper we propose Fed-ensemble: a simple approach that bringsmodel ensembling to federated learning (FL).

ScrofaZero: Mastering Trick-taking Poker Game Gongzhu by Deep Reinforcement Learning

1 code implementation15 Feb 2021 Naichen Shi, Ruichen Li, Sun Youran

Since trick-taking game requires high level of not only reasoning, but also inference to excel, it can be a new milestone for imperfect information game AI.

RMSprop can converge with proper hyper-parameter

no code implementations ICLR 2021 Naichen Shi, Dawei Li, Mingyi Hong, Ruoyu Sun

Removing this assumption allows us to establish a phase transition from divergence to non-divergence for RMSProp.
