Breaking Algorithmic Collusion in Human-AI Ecosystems

arXiv:2511.21935v1 Announce Type: new Abstract: AI agents are increasingly deployed in ecosystems where they repeatedly interact not only with each other but also with humans. In this work, we study these human-AI ecosystems from a theoretical perspective, focusing on the…

Deep Learning Architectures for Code-Modulated Visual Evoked Potentials Detection

arXiv:2511.21940v1 Announce Type: new Abstract: Non-invasive Brain-Computer Interfaces (BCIs) based on Code-Modulated Visual Evoked Potentials (C-VEPs) require highly robust decoding methods to address temporal variability and session-dependent noise in EEG signals. This study proposes and evaluates several deep learning architectures,…

Revisiting Frank-Wolfe for Structured Nonconvex Optimization

arXiv:2503.08921v2 Announce Type: replace-cross Abstract: We introduce a new projection-free (Frank-Wolfe) method for optimizing structured nonconvex functions that are expressed as a difference of two convex functions. This problem class subsumes smooth nonconvex minimization, positioning our method as a promising…

PointMapPolicy: Structured Point Cloud Processing for Multi-Modal Imitation Learning

arXiv:2510.20406v2 Announce Type: replace-cross Abstract: Robotic manipulation systems benefit from complementary sensing modalities, where each provides unique environmental information. Point clouds capture detailed geometric structure, while RGB images provide rich semantic context. Current point cloud methods struggle to capture fine-grained…
