此改变使其在较小批量上比CLIP具有更好的零样本性能。 潜在语言图像预训练(Latent language image pretraining,Llip)考虑到一张图像可以有多种不同的标题。它通过交叉注意模块将图像的编码与目标标题关联。考虑标题的多样性增加了表示的表达性,并且通常提高了零样本分类和检索性能。 具有掩码目标的VLMs 掩码是一种在...
但仍然要求下游任务提供有标签数据并需要训练过程。 引出Vision-Language Model Pre-training and Zero-shot Prediction In this paradigm, a vision-language model (VLM) is pre-trained with large-scale image-text pairs that are almost infinitely available on the internet, and the pre-trained VLM can be...
stage, we can only access data from Db and E for model training. The target is to build a unified classifier for all seen classes Yb = Y1 ∪··· Yb continually. In other words, we hope to find a model f(x) : X → Yb that minimizes the expected risk: f∗ = argmin f∈H ...
In this work, we introduce EchoCLIP, a foundation model for echocardiography trained on a dataset of 1,032,975 echocardiogram videos sourced from over a decade of clinical imaging. We developed a method for substantially compressing echocardiography reports, simplifying the matching of clinical text a...
本文受到前人对抗训练方法的启发,将其用到 vision-language model 的预训练中。 该方法的核心部分有如下三点: 对抗的预训练和微调机制; 在映射空间添加干扰; 增强的对抗训练方法; 1. 对抗预训练与微调: Pre-training: 给定预训练数据集,包含 image-text pairs,训练的目标就是在这个大型数据集上学习一些与任务无...
Microsoft will release the VinVL model and the source code to the public. Please refer to the research paper and GitHub repository. In addition, VinVL is being integrated into the Azure Cognitive Services, powering a wide range of multimodal scenarios (such as Seeing AI, Image Captioning...

⚠️It is important to be mindful of your model's token limit.GPT-4o does not work with too many images in the prompt (see discussionhere). To remedy this issue, either use an LLM with a larger context window, extract larger documents withtext_only=True, or embed the chunks into ...
在每个 level，问题的特征与图像还有 facts 再一起 jointly embed 在一个空间当中，通过一个 co-attention model。这里的 facts 是一系列的，利用现有计算机视觉模型所提取出的图像信息。最后，我们用一个 MLP 去预测答案，基于每一层的 co-attention model 的输出。那么回答问题的原因是通过对加权后的 facts 进行...
