Semantically Grounded Evaluation For Open-Vocabulary Human-Object Interaction Detection, Maja Noack

Electronic Theses and Dissertations

Open-vocabulary human–object interaction (HOI) detection is a step towards building scal¬able systems that generalize to unseen interactions in real-world scenarios and support grounded multimodal systems that reason about human–object relationships. However, stan¬dard evaluation metrics, such as mean Average Precision (mAP), treat HOI classes as dis¬crete categorical labels and fail to credit semantically valid but lexically different predictions (e.g., “lean on couch” vs. “sit on couch”), limiting their applicability for evaluating open-vocabulary predictions that go beyond any predefined set of HOI labels. I introduce SHOE (Semantic HOI Open-Vocabulary Evaluation), a new evaluation framework that incorporates semantic similarity between predicted and ground-truth …
