Change Point Localization and Inference in Dynamic Multilayer Networks

Fan Wang, Kyle Ritscher, Yik Lun Kei, Xin Ma, OSCAR HERNAN MADRID PADILLA

ICLR 2026poster

We study offline change point localization and inference in dynamic multilayer random dot product graphs (D-MRDPGs), where at each time point, a multilayer network is observed with shared node latent positions and time-varying, layer-specific connectivity patterns. We propose a novel two-stage algor…

We study the machine's understanding of embodied reference: One agent uses both language and gesture to refer to an object to another agent in a shared physical environment. Of note, this new visual task requires understanding multimodal cues with perspective-taking to identify which object is being…
