Verb-noun decomposition offers limited generalization in action recognition

By PulseAugur Editorial · [1 sources] ·

A new research paper analyzes the effectiveness of verb-noun decomposition in assembly action recognition, a method used to predict novel combinations of familiar components. The study, conducted across three datasets (MECCANO, HAViD, and IMPACT), found that while decomposition improves performance beyond basic atomic action classification, its generalization is limited. Performance remains heavily influenced by the co-occurrence patterns in the training data, suggesting that gains are often due to interpolation rather than true unconstrained recombination. The research also identified vocabulary asymmetry and component entanglement as key sources of error, proposing a diagnostic framework to study compositional recognition. AI

IMPACT Identifies limitations in current compositional generalization techniques for AI models, suggesting areas for improvement in action recognition systems.

    Reachability Is Not Generalization: Understanding Verb--Noun Decomposition in Assembly Action Recognition

    arXiv:2610.00064v1 Announce Type: new Abstract: Assembly actions are compositional: they combine a manipulation with a part or tool. In deployment, systems routinely encounter novel combinations of familiar components, yet an atomic action classifier assigns every unseen combinat…
