    LLM-Guided ANN Index Optimization for Human-Object Interaction Retrieval

    Researchers have developed a novel LLM-guided agent for optimizing Approximate Nearest Neighbor (ANN) index parameters in retrieval systems. This agent overcomes the limitations of traditional hyperparameter optimization methods by conditioning each proposal on the full optimization history, effectively navigating complex, coupled parameter spaces. Tested on the HICO-DET human-object interaction retrieval benchmark, the agent demonstrated significant performance gains, outperforming existing methods by over 33% and achieving a 15.3x throughput increase. AI

    IMPACT This LLM-guided optimization method could significantly improve the efficiency and performance of various AI retrieval systems.

    ScriptHOI: Learning Scripted State Transitions for Open-Vocabulary Human-Object Interaction Detection

    Researchers have developed ScriptHOI, a novel framework for open-vocabulary human-object interaction detection. This approach decomposes interaction phrases into specific state slots like body-role and contact, enabling a more nuanced understanding beyond simple co-occurrence. ScriptHOI utilizes a visual state tokenizer and slot-wise matching to assess script coverage and conflict, improving recognition of rare interactions and reducing false positives. The method also incorporates interval partial-label learning to better handle incomplete annotations. AI
