Asymptotic tracking control of dynamic reference over homomorphically encrypted data with finite modulus

no code implementations27 Sep 2024 Shuai Feng, Junsoo Kim

Leveraging the property above, we design an algorithm on the actuator side such that it can restore the control input from the lower bits under a finite modulus.

SeMOPO: Learning High-quality Model and Policy from Low-quality Offline Visual Datasets

no code implementations13 Jun 2024 Shenghua Wan, ZiYuan Chen, Le Gan, Shuai Feng, De-Chuan Zhan

Model-based offline reinforcement Learning (RL) is a promising approach that leverages existing data effectively in many real-world applications, especially those involving high-dimensional inputs like images and videos.

SENSOR: Imitate Third-Person Expert's Behaviors via Active Sensoring

no code implementations4 Apr 2024 Kaichen Huang, Minghao Shao, Shenghua Wan, Hai-Hang Sun, Shuai Feng, Le Gan, De-Chuan Zhan

In many real-world visual Imitation Learning (IL) scenarios, there is a misalignment between the agent's and the expert's perspectives, which might lead to the failure of imitation.

DIDA: Denoised Imitation Learning based on Domain Adaptation

no code implementations4 Apr 2024 Kaichen Huang, Hai-Hang Sun, Shenghua Wan, Minghao Shao, Shuai Feng, Le Gan, De-Chuan Zhan

Imitating skills from low-quality datasets, such as sub-optimal demonstrations and observations with distractors, is common in real-world applications.

AD3: Implicit Action is the Key for World Models to Distinguish the Diverse Visual Distractors

no code implementations15 Mar 2024 Yucen Wang, Shenghua Wan, Le Gan, Shuai Feng, De-Chuan Zhan

Model-based methods have significantly contributed to distinguishing task-irrelevant distractors for visual control.

Quantized distributed Nash equilibrium seeking under DoS attacks

no code implementations24 Aug 2023 Shuai Feng, Maojiao Ye, Lihua Xie, Shengyuan Xu

To solve the quantizer saturation problem caused by DoS attacks, the quantization mechanism is equipped to have zooming-in and holding capabilities, in which the holding capability is consistent with the results in quantized consensus under DoS.

Krasovskii and Shifted Passivity Based Output Consensus

no code implementations4 Jul 2022 Yu Kawano, Michele Cucuzzella, Shuai Feng, Jacquelien M. A. Scherpen

Motivated by current sharing in power networks, we consider a class of output consensus (also called agreement) problems for nonlinear systems, where the consensus value is determined by external disturbances, e. g., power demand.

READ: Aggregating Reconstruction Error into Out-of-distribution Detection

no code implementations15 Jun 2022 Wenyu Jiang, Yuxin Ge, Hao Cheng, Mingcai Chen, Shuai Feng, Chongjun Wang

We propose a novel method, READ (Reconstruction Error Aggregated Detector), to unify inconsistencies from classifier and autoencoder.

The Flare and Warp of the Young Stellar Disk traced with LAMOST DR5 OB-type stars

no code implementations1 Feb 2021 Yang Yu, Hai-Feng Wang, Wen-Yuan Cui, Lin-Lin Li, Chao Liu, Bo Zhang, Hao Tian, Zhen-Yan Huo, Jie Ju, Zhi-Cun Liu, Fang Wen, Shuai Feng

We present analysis of the spatial density structure for the outer disk from 8$-$14 \, kpc with the LAMOST DR5 13534 OB-type stars and observe similar flaring on north and south sides of the disk implying that the flaring structure is symmetrical about the Galactic plane, for which the scale height at different Galactocentric distance is from 0. 14 to 0. 5 \, kpc.
