Multi-stage feature decorrelation constraints for improving CNN classification performance

1 code implementation24 Aug 2023 Qiuyu Zhu, Hao Wang, Xuewen Zu, Chengfei Liu

Considering that there are many layers in CNN, through experimental comparison and analysis, MFD Loss acts on multiple front layers of CNN, constrains the output features of each layer and each channel, and performs supervision training jointly with classification loss function during network training.

CHIEF: Clustering with Higher-order Motifs in Big Networks

no code implementations6 Apr 2022 Feng Xia, Shuo Yu, Chengfei Liu, Ivan Lee

In the first procedure, we propose to lower the network scale by optimizing the network structure with maximal k-edge-connected subgraphs.

By exploiting the discoveries, we propose novel algorithms for maintaining the two indices, which substantially reduces the cost of maintenance.

Index-based Solutions for Efficient Density Peak Clustering

no code implementations8 Feb 2020 Zafaryab Rasool, Rui Zhou, Lu Chen, Chengfei Liu, Jiajie Xu

Efficient query algorithms are proposed for these indices which significantly avoids irrelevant comparisons at the cost of space.
