Adaptive higher-order contagion of harmful information with platform-induced group dissolution and individual rewiring
Longzhao Liu, Zhihao Han, Xingru Chen +4
Curbing harmful information contagion remains a critical challenge, motivating platform-level interventions such as group dissolution to sever transmission chains. However, in prac…
Toward Annotation-Efficient Continuous Emotion Arousal Quantification via Group-Level EEG Dynamic Neural Synchrony
Guandong Pan, Yaqian Yang, Shi Chen +4
The paper proposes using group-level EEG dynamic neural synchrony as a signal to continuously quantify emotional arousal without needing per‑subject manual annotations, showing tha…
Immunization on Temporal Higher-Order Networks
Zhihao Han, Longzhao Liu, Xin Wang +3
Network immunization is a powerful tool for controlling contagion processes ranging from infectious diseases to misinformation diffusion. While prior works have focused on pairwise…
Learning to Erase Private Knowledge from Multi-Documents for Retrieval-Augmented Large Language Models
Yujing Wang, Jinwen Chen, Hainan Zhang +5
Retrieval-Augmented Generation (RAG) is a promising technique for applying LLMs to proprietary domains. However, retrieved documents may contain sensitive knowledge, posing risks o…
Identifying vulnerable nodes for hypergraph dismantling via higher-order competition dynamics
Yajing Hao, Longzhao Liu, Xin Wang +3
Network dismantling aims to identify a node removal sequence that can rapidly destroy network connectivity, which is an important problem for understanding the structural fragility…
Emergent dilemma and periodic oscillation in the nonlinear interplay between epidemic and behavior
Longzhao Liu, Hongwei Zheng, Yajing Hao +3
Human behaviors, particularly non-pharmaceutical interventions (NPIs), are dynamically coupled with epidemic spreading. While prior studies mainly assume a linear interplay, real-w…
