ColPali: A new approach to efficient and intelligent document retrieval 🚀
Our latest research paper, "ColPali: Efficient Document Retrieval with Vision Language Models," introduces a groundbreaking approach to large-scale visual document analysis. By leveraging Vision Language Models (VLMs), we have created a new framework for document retrieval that's both powerful and efficient.
Key Insights:
💡 ColPali combines ColBERT's multi-vector strategy with VLMs' document understanding capabilities
⚙️ ColPali is based on PaliGemma-3B (SigLIP, Gemma-2B) + a linear projection layer and is trained to maximize the similarity between the document and the query embeddings
📊 The Vision Document Retrieval benchmark (ViDoRe) is a challenging dataset that spans various industry topics and aims at matching real-life retrieval scenarios
🏆 ColPali outperforms existing models on all datasets in ViDoRe (average NDCG@5 of 81.3% vs 67.0% for the best baseline model)
⚡ ColPali is faster at document embedding compared to traditional PDF parser pipelines, making ColPali viable for industrial use
🔍 ColPali is highly interpretable thanks to patch-based similarity maps
