ColPali: Visual Retriever based on PaliGemma-3B with ColBERT strategy

ColQwen is a model based on a novel model architecture and training strategy based on Vision Language Models (VLMs) to efficiently index documents from their visual features. It is a Qwen2-VL-2B extension that generates ColBERT - style multi-vector representations of text and images. It was introduced in the paper ColPali: Efficient Document Retrieval with Vision Language Models and first released in this repository

This version is the untrained base version to guarantee deterministic projection layer initialization.

Usage

This version should not be used, it is solely the base version useful for deterministic LoRA initialization !
