On the Detection of Commutative Factors in Factor Graphs: Necessary and Sufficient Conditions
Researchers have identified critical flaws in the state-of-the-art algorithm for detecting commutative factors in factor graphs, a foundational technique for lifted probabilistic inference. The algorithm incorrectly treats a necessary condition as sufficient, potentially producing incorrect results. The authors provide corrected algorithms that maintain efficiency while ensuring correctness.
