• mPLUG-Owl2 Revolutionizing Multi-modal Large Language Model with Modality Collaboration (11 Nov 2023)
  

  This is my reading note for mPLUG-Owl2: Revolutionizing Multi-modal Large Language Model with Modality Collaboration. This paper proposes a method to unify visual and text data for multi modal model. To this end, it uses QFormer to extract visual information and concatenate to text and feed to LLM. However, it separates the projection layer and layer norm for visual and text. This paper is similar to COGVLM.

• CogVLM Visual Expert for Pretrained Language Models (10 Nov 2023)
  

  This is my reading note for CogVLM: Visual Expert for Pretrained Language Models. This paper proposes a vision language model similarly to mPLUG-OWL2. To avoid impacting the performance of LLM, it proposes a visual adapter which adds visual specific projection layer to each attention and feed forward layer.

• A Picture is Worth a Thousand Words Principled Recaptioning Improves Image Generation (28 Oct 2023)
  

  This is my reading note for A Picture is Worth a Thousand Words: Principled Recaptioning Improves Image Generation. The papers found that the text data used to train text to image model is now quality, which is based alt text of images.it proposed to use an image caption model to generate high quality text for the images; then the diffusion model trained from this new text data show much better performance.

• PaLI-3 Vision Language Models Smaller, Faster, Stronger (15 Oct 2023)
  

  This is reading note for PaLI-3 Vision Language Models: Smaller, Faster, Stronger. This paper proposes to use image-text-matching to replace contrast loss. The experiment indicates this method is especially effective in relatively small models.

• Qwen-VL A Versatile Vision-Language Model for Understanding, Localization, Text Reading, and Beyond (09 Jul 2023)
  

  This is my reading note for Qwen-VL: A Versatile Vision-Language Model for Understanding, Localization, Text Reading, and Beyond. This paper proposes a vision-language model capable of vision grounding and image text reading. To do that, it considers visual grounding and OCR tasks in pre-training. In architecture, the paper uses Qformer from BLIP2.

• PaLI A Jointly-Scaled Multilingual Language-Image Model (08 Jul 2023)
  

  This is my reading note for PaLI: A Jointly-Scaled Multilingual Language-Image Model. This paper formulates all the image-text pretraining tasks as visual question answering. The major contributions of this paper includes 1) shows balanced size of vision model and language model improves performances; 2) training with mixture of 8 tasks is important.
