Scaling properties in spatial networks and its effects on topology and traffic dynamics
Hua Yang, Yuchao Nie, Ying Fan +2
Empirical studies on the spatial structures in several real transport networks reveal that the distance distribution in these networks obeys power law. To discuss the influence of…
Effects of Weight on Structure and Dynamics in Complex Networks
Menghui Li, Ying Fan, Dahui Wang +4
Link weight is crucial in weighted complex networks. It provides additional dimension for describing and adjusting the properties of networks. The topological role of weight is stu…
Optimizing DDPM Sampling with Shortcut Fine-Tuning
Ying Fan, Kangwook Lee
In this study, we propose Shortcut Fine-Tuning (SFT), a new approach for addressing the challenge of fast sampling of pretrained Denoising Diffusion Probabilistic Models (DDPMs). S…
Detecting the optimal number of communities in complex networks
Zhifang Li, Yanqing Hu, Beishan Xu +2
To obtain the optimal number of communities is an important problem in detecting community structure. In this paper, we extend the measurement of community detecting algorithms to…
Dion: Distributed Orthonormalized Updates
Kwangjun Ahn, Byron Xu, Natalie Abreu +5
Orthonormalized updates accelerate training, improve stability, and enable robust hyperparameter transfer, but existing methods like Muon rely on dense matrix operations that clash…
Societal citations undermine the function of the science reward system
Xiaokai Li, An Zeng, Ying Fan
Citations in the scientific literature system do not simply reflect relationships between knowledge but are influenced by non-objective and societal factors. Citation bias, irrespo…
