UCDFormer: Unsupervised Change Detection Using a Transformer-driven Image Translation

1 code implementation2 Aug 2023 Qingsong Xu, Yilei Shi, Jianhua Guo, Chaojun Ouyang, Xiao Xiang Zhu

Specifically, a transformer-driven image translation composed of a light-weight transformer and a domain-specific affinity weight is first proposed to mitigate domain shift between two images with real-time efficiency.

Limiting laws and consistent estimation criteria for fixed and diverging number of spiked eigenvalues

no code implementations15 Dec 2020 Jianwei Hu, Jingfei Zhang, Ji Zhu, Jianhua Guo

Firstly, for fixed $p$, we propose a generalized estimation criterion that can consistently estimate, $k$, the number of spiked eigenvalues.

Fast Network Community Detection with Profile-Pseudo Likelihood Methods

1 code implementation1 Nov 2020 Jiangzhou Wang, Jingfei Zhang, Binghui Liu, Ji Zhu, Jianhua Guo

In this article, we propose a novel likelihood based approach that decouples row and column labels in the likelihood function, which enables a fast alternating maximization; the new method is computationally efficient, performs well for both small and large scale networks, and has provable convergence guarantee.
