Open-set GNNs silently break when graphs violate homophily, but synthesizing pseudo-unknown proxies along cross-class displacement vectors restores robust out-of-distribution detection on heterophilic topologies.

PPRC achieves unprecedented efficiency and accuracy in range counting over overlapping datasets while ensuring query privacy, outperforming existing protocols by a wide margin.

LLM-powered task bots leak training data like travel schedules with alarming precision, demanding new defenses.
