PreAfford: Universal Affordance-Based Pre-Grasping for Diverse Objects and Environments

no code implementations4 Apr 2024 Kairui Ding, Boyuan Chen, Ruihai Wu, Yuyang Li, Zongzheng Zhang, Huan-ang Gao, Siqi Li, Yixin Zhu, Guyue Zhou, Hao Dong, Hao Zhao

Robotic manipulation of ungraspable objects with two-finger grippers presents significant challenges due to the paucity of graspable features, while traditional pre-grasping techniques, which rely on repositioning objects and leveraging external aids like table edges, lack the adaptability across object categories and scenes.

Hypergraph-based Multi-View Action Recognition using Event Cameras

no code implementations28 Mar 2024 Yue Gao, Jiaxuan Lu, Siqi Li, Yipeng Li, Shaoyi Du

By treating segments as vertices and constructing hyperedges using rule-based and KNN-based strategies, a multi-view hypergraph neural network that captures relationships across viewpoint and temporal features is established.

AutoDFP: Automatic Data-Free Pruning via Channel Similarity Reconstruction

no code implementations13 Mar 2024 Siqi Li, Jun Chen, Jingyang Xiang, Chengrui Zhu, Yong liu

AutoDFP assesses the similarity of channels for each layer and provides this information to the reinforcement learning agent, guiding the pruning and reconstruction process of the network.

CR-SFP: Learning Consistent Representation for Soft Filter Pruning

no code implementations17 Dec 2023 Jingyang Xiang, Zhuangzhi Chen, Jianbiao Mei, Siqi Li, Jun Chen, Yong liu

In this paper, we propose to mitigate this gap by learning consistent representation for soft filter pruning, dubbed as CR-SFP.

MaxQ: Multi-Axis Query for N:M Sparsity Network

1 code implementation12 Dec 2023 Jingyang Xiang, Siqi Li, JunHao Chen, Zhuangzhi Chen, Tianxin Huang, Linpeng Peng, Yong liu

Meanwhile, a sparsity strategy that gradually increases the percentage of N:M weight blocks is applied, which allows the network to heal from the pruning-induced damage progressively.

SUBP: Soft Uniform Block Pruning for 1xN Sparse CNNs Multithreading Acceleration

1 code implementation10 Oct 2023 Jingyang Xiang, Siqi Li, Jun Chen, Shipeng Bai, Yukai Ma, Guang Dai, Yong liu

To overcome them, this paper proposes a novel \emph{\textbf{S}oft \textbf{U}niform \textbf{B}lock \textbf{P}runing} (SUBP) approach to train a uniform 1$\times$N sparse structured network from scratch.

FedScore: A privacy-preserving framework for federated scoring system development

1 code implementation1 Mar 2023 Siqi Li, Yilin Ning, Marcus Eng Hock Ong, Bibhas Chakraborty, Chuan Hong, Feng Xie, Han Yuan, Mingxuan Liu, Daniel M. Buckland, Yong Chen, Nan Liu

We also calculated the average AUC values and SDs for each local model, and the FedScore model showed promising accuracy and stability with a high average AUC value which was closest to the one of the pooled model and SD which was lower than that of most local models.

UFO2: A unified pre-training framework for online and offline speech recognition

no code implementations26 Oct 2022 Li Fu, Siqi Li, Qingtao Li, Liping Deng, Fangzhu Li, Lu Fan, Meng Chen, Xiaodong He

In this paper, we propose a Unified pre-training Framework for Online and Offline (UFO2) Automatic Speech Recognition (ASR), which 1) simplifies the two separate training workflows for online and offline modes into one process, and 2) improves the Word Error Rate (WER) performance with limited utterance annotating.
