Global Spectral Filter Memory Network for Video Object Segmentation

1 code implementation11 Oct 2022 Yong liu, Ran Yu, Jiahao Wang, Xinyuan Zhao, Yitong Wang, Yansong Tang, Yujiu Yang

Besides, we empirically find low frequency feature should be enhanced in encoder (backbone) while high frequency for decoder (segmentation head).

A Hybrid Self-Supervised Learning Framework for Vertical Federated Learning

1 code implementation18 Aug 2022 Yuanqin He, Yan Kang, Xinyuan Zhao, Jiahuan Luo, Lixin Fan, Yuxing Han, Qiang Yang

In this work, we propose a Federated Hybrid Self-Supervised Learning framework, named FedHSSL, that utilizes cross-party views (i. e., dispersed features) of samples aligned among parties and local views (i. e., augmentation) of unaligned samples within each party to improve the representation learning capability of the VFL joint model.

Learning Quality-aware Dynamic Memory for Video Object Segmentation

1 code implementation16 Jul 2022 Yong liu, Ran Yu, Fei Yin, Xinyuan Zhao, Wei Zhao, Weihao Xia, Yujiu Yang

However, they mainly focus on better matching between the current frame and the memory frames without explicitly paying attention to the quality of the memory.

THOR, Trace-based Hardware-adaptive layer-ORiented Natural Gradient Descent Computation

no code implementations AAAI Technical Track on Machine Learning 2021 Mengyun Chen, Kaixin Gao, Xiaolei Liu, Zidong Wang, Ningxi Ni, Qian Zhang, Lei Chen, Chao Ding, ZhengHai Huang, Min Wang, Shuangling Wang, Fan Yu, Xinyuan Zhao, Dachuan Xu

It is well-known that second-order optimizer can accelerate the training of deep neural networks, however, the huge computation cost of second-order optimization makes it impractical to apply in real practice.

Matrix optimization based Euclidean embedding with outliers

no code implementations23 Dec 2020 Qian Zhang, Xinyuan Zhao, Chao Ding

Euclidean embedding from noisy observations containing outlier errors is an important and challenging problem in statistics and machine learning.
