AgentCue: Statistical Summaries for Guiding Decentralized Multi-Agent Self-Organization
Guojun Zhu, Xinyou Chen, Kejian Zhang +2
Multi-agent systems (MAS) combine multiple agents to solve complex tasks, and recent MAS scale to more than a thousand agents. At this scale, decentralized MAS remove the central o…
Pattern-Calibrated Multimodal Prediction under Blockwise Missingness
Junhan Yu, Kejian Zhang, Doudou Zhou +1
Blockwise missingness in multimodal data is usually treated as an incomplete-input problem. We instead focus on prediction for a prespecified observed-modality pattern, where the o…
From Hawkes Processes to Attention: Time-Modulated Mechanisms for Event Sequences
Xinzi Tan, Kejian Zhang, Junhan Yu +1
Marked Temporal Point Processes (MTPPs) arise naturally in medical, social, commercial, and financial domains. However, existing Transformer-based methods mostly inject temporal in…
Two-sample Testing with Block-wise Missingness in Multi-source Data
Kejian Zhang, Muxuan Liang, Robert Maile +1
Multi-source and multi-modal datasets are increasingly common in scientific research, yet they often exhibit block-wise missingness, where entire modalities are systematically abse…
