Researchers have introduced WIDE (Wildcard Inference with Dynamic Expansion), a novel approach to enhance cross-modal generative retrieval. This method addresses the challenge of information asymmetry between modalities, such as text and images, which can lead to inaccurate rankings due to forced hallucination in autoregressive decoders. WIDE utilizes Adaptive Entropy Thresholding to set uncertainty boundaries and Asymmetry-aware Wildcard Decoding to replace deterministic identifiers with wildcards, dynamically broadening the search space. A final Blind-Spot Re-ranking step combines generation confidence with semantic similarity to evaluate the expanded candidates, demonstrating superior performance on the M-BEIR benchmark. AI
