ColPali: Document Retrieval with Vision-Language Models only (with Manuel Faysse)
34:48 Share

In this episode of Neural Search Talks, we're chatting with Manuel Faysse, a 2nd year PhD student from CentraleSupélec & Illuin Technology, who is the first author of the paper "ColPali: Efficient Document Retrieval with Vision Language Models". ColPali is making waves in the IR community as a simple but effective new take on embedding documents using their image patches and the late-interaction paradigm popularized by ColBERT. Tune in to learn how Manu conceptualized ColPali, his methodology for tackling new research ideas, and why this new approach outperforms all classic multimodal embedding models. A must-watch episode!
