5CD-AI/ColVintern-1B-v1

ColVintern-1B-v1 🇻🇳 ❄️ - Colpali version for Vietnamese.

What's new in ColVintern-1B-v1!

• We coded and successfully trained the Colpali pipeline for Vintern-1B-v2. The model supports RAG by extracting embedding vectors for questions and images containing related information.
• This is the first experimental version, trained on the Colpali dataset for English and 5% of the image-based question-answer pairs we have for Vietnamese.
• The model achieves results nearly equivalent to Colpali version 1, with strong support for Vietnamese texts and only 1 billion parameters compared to current 2B-3B Colpali models.

Colpali Benchmarks

We tested on the ViDoRe benchmark from the Colpali paper. The TabF and Shift test datasets were not used because they are in French. We plan to expand to multiple languages in the near future.

We are expanding the training dataset for upcoming versions, including adding hard negative mining techniques, increasing GPU VRAM, etc., to achieve better results.
