English(EN) PUMA: Post-Hoc Sparsification of Universal Multimodal Embeddings for Efficient Retrieval

新的PUMA方法稀疏化多模态嵌入以实现高效检索

作者 PulseAugur 编辑部 · [1 个来源] ·

研究人员开发了PUMA，一种用于通用多模态嵌入后验稀疏化的新颖方法。该技术通过将密集嵌入映射到紧凑的稀疏代码，而无需重新训练骨干模型，从而显著降低了多模态检索相关的内存和推理成本。PUMA已在Qwen3-VL-Embedding-2B模型基准测试中证明了其有效性，实现了相当或更优的检索性能，同时将存储成本降低了8-16倍，并将速度提高了25倍。 AI

影响 通过降低计算成本，实现更高效、可扩展的多模态检索系统。

    PUMA：通用多模态嵌入的后验稀疏化，用于高效检索

    Universal multimodal embedders enable retrieval across text, image, and combined queries, but their dense representations incur high memory and inference costs. Post-hoc sparsification could reduce these costs but remains underexplored for multimodal retrieval. We introduce PUMA,…
