Researchers have identified a phenomenon called distance-misaligned training in Graph Transformers, where the model's communication allocation doesn't match the location of relevant information for a given task. They developed a synthetic benchmark to study this, finding that the optimal communication distance bias varies with task locality. An adaptive controller, informed by the task's distance target, significantly improved performance over a baseline, highlighting the importance of task-specific control. AI
