A team from Peking University and Georgia Tech has built a formal theory explaining why the most widely used GNN approach to multi-node tasks breaks down — and proved that a simple but principled labeling strategy solves the problem completely.

In today’s rapidly evolving industrial landscape, product design and manufacturing systems (PDMS) face an unprecedented challenge: making sense of vast, interconnected data while dealing with incomplete knowledge bases. Knowledge graphs have emerged as the backbone of intelligent manufacturing, structuring complex…
Every cortex is folded in its own particular way. The overall pattern of ridges and grooves, called gyri and sulci, is recognizable from one person to the next, but the exact shape, depth, and location of any given fold varies…
