• ConvNets Match Vision Transformers at Scale (01 Nov 2023)
  

  This is my reading note for ConvNets Match Vision Transformers at Scale. This paper shows that given same scale of data and same amount of train resources, CNN could perform similarly as transformer. A similarly observation was reported in # Battle of the Backbones A Large-Scale Comparison of Pretrained Models across Computer Vision Tasks

• Battle of the Backbones A Large-Scale Comparison of Pretrained Models across Computer Vision Tasks (29 Oct 2023)
  

  This is my reading note for Battle of the Backbones: A Large-Scale Comparison of Pretrained Models across Computer Vision Tasks. This paper benchmarks different vision backbones and found that supervised ConvNext may show best performance. After it, supervised swin-transformer and clip based transformer is also very competitive. Different vision tasks shows highly correlated performance for different backbones.

• Flamingo a Visual Language Model for Few-Shot Learning (26 Oct 2023)
  

  This is my reading note for Flamingo: a Visual Language Model for Few-Shot Learning. This paper proposes to formulate vision language model vs text prediction task given existing text and visual. The model utilizes frozen visual encoder and LLM, and only fine tune the visual adapter (perceiver). The ablation study strongly against fine tune/retrain those components.

• 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.

• Small-scale proxies for large-scale Transformer training instabilities (09 Oct 2023)
  

  This is my reading note for Small-scale proxies for large-scale Transformer training instabilities. This paper discusses the method to improve model training stability related to hyper parameter.

• Vision Transformers Need Registers (29 Sep 2023)
  

  This is my reading note for Vision Transformers Need Registers. This paper analyzes the attention map of transformer and find too large scale transformer and trained after a long iteration, some token show exceptionally high norm. Those tokens usually correspond to patches in uniform background. Analysis indicates that those tokens are used to store global information. Thus at would heart dense prediction tasks like image segmentation. To tackle this, the paper proposes add additional tokens during trains and inference, but rejecting for outputs.

• Scaling Vision Transformers (23 Sep 2023)
  

  This is my reading note for Scaling Vision Transformers. This paper provides a detailed comparison and study of designing vision transformer.

• An Empirical Study of Training End-to-End Vision-and-Language Transformers (21 Sep 2023)
  

  This is my reading note for An Empirical Study of Training End-to-End Vision-and-Language Transformers. This paper provides a good review and comparison of multi modality (video and text) model’s design choice.

• DualToken-ViT Position-aware Efficient Vision Transformer with Dual Token Fusion (03 Aug 2023)
  

  This is my reading note for DualToken-ViT Position-aware Efficient Vision Transformer with Dual Token Fusion. The paper discuss efficient transformer, which is based on combining convolution with attention: where convolution extracts local information and then fused with global information via attention.

• FLAVA A Foundational Language And Vision Alignment Model (30 Jul 2023)
  

  This is my reading note for FLAVA: A Foundational Language And Vision Alignment Model. This paper proposes a multi modality model. Especially, the model not only work across modality, but also on each modality and joint modality. To do that, it contains loss functions for both within modality but also across modality. It also proposes to use the same architecture for vision encoder, Text encoder as well as multi -modality encoder.

• 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.

• Tag2Text Guiding Vision-Language Model via Image Tagging (21 Jun 2023)
  

  This is my reading note for Tag2Text: Guiding Vision-Language Model via Image Tagging. This paper proposes to add tag recognition to vision language model and shows improved performance.

• ViT AN IMAGE IS WORTH 16X16 WORDS TRANSFORMERS FOR IMAGE RECOGNITION AT SCALE (28 Mar 2021)
  

  Vision Transformer (ViT) is a pure transformer architecture (no CNN is required) applied directly to a sequence of image patches for classification tasks. The order of patches in sequence capture the spatial information of those patches, similar to words in sentences.
