This is my reading note for DiffusionDet: Diffusion Model for Object Detection. This paper formulates the object detection problem as a diffusion process: recover object bounding box from noisy estimation. The initial estimation could be from purely random Gaussian noise. One benefit of this method is that it could automatically handle different number of bounding boxes
This is my reading note for Efficient Streaming Language Models with Attention Sinks. This paper proposes a method to extend a LLM to infinite length text. This method is based on sliding attention plus prepending four sink tokens to aggregate global information. This paper shares similar idea as Vision Transformers Need Registers, which adds addition token to capture global information in attention.
This is my reading note for Leveraging Unpaired Data for Vision-Language Generative Models via Cycle Consistency. The papers proposes a method to train a multi modality model between text and image. Especially, the paper propose cycle consistency loss to leverage unpaired text and image: use image to generate text and use text to recover image and vice verse. It reminds me cycle-GAN paper.
This is my reading note for An Early Evaluation of GPT-4V(ision). The highlights of our findings are as follows:
- GPT-4V exhibits impressive performance on English visual-centric benchmarks but fails to recognize simple Chinese texts in the images;
- GPT-4V shows inconsistent refusal behavior when answering questions related to sensitive traits such as gender, race, and age;
- GPT-4V obtains worse results than GPT-4 (API) on language understanding tasks including general language understanding benchmarks and visual commonsense knowledge evaluation benchmarks;
- Few-shot prompting can improve GPT-4V’s performance on both visual understanding and language understanding;
- GPT-4V struggles to find the nuances between two similar images and solve the easy math picture puzzles;
- GPT-4V shows non-trivial performance on the tasks of similar modalities to image, such as video and thermal. O (p. 1)
This is my reading note for Raising the Cost of Malicious AI-Powered Image Editing. This paper proposes a method to stop an image being edited by on diffusion model. The method is based on adverbial attack: learn a perturbation to the target image such that the model (encoder or diffusion) will generate noise or degraded image. However this method may not always work or may fall when the model changes.
This is my reading note for Aligning Large Multimodal Models with Factually Augmented RLHF. This paper discusses how to mitigate hallucination for large multimodal model.it proposes two methods, 1) add additional human labeled data to train a reward model to guide the fine tune of the final model: 2) add additional factual data to the reward model besides model’s response.
This is my reading note for DeepSpeed-VisualChat: Multi-Round Multi-Image Interleave Chat via Multi-Modal Causal Attention. This paper proposes a method for multi round multi-image multi modality model. The paper utilizes a frozen LLM and visual encoder. The contribution of the paper includes: 1. Casual cross attention method to combine image and multiround text; 2. A new dataset.
This is my reading note for Demystifying CLIP Data. This paper reverse engineered the data of CLIP and replicated even outperformed the CLIP.
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.
