对于纯文本数据,VLMo采用了BERT [6]的掩码语言模型(Masked Language Model,MLM)进行模型的预训练。对于纯图像数据,VLMo采用了BEiT[7]的掩码图像模型(Maksed Image Model,MIM)进行预训练。 2.2.2 多模态数据训练 (1)对比学习 给定N个图像文本对,根据对比学习的思想我们可以构建N^2个不同的样本,其中N个正样本...
在探讨BEiT v3之前，我们先来了解董力团队研发的VLMo（Vision Language pretrained Model），一个在多模态预训练领域具有创新性的模型。VLMo的核心是MoME-Transformer，即混合模态专家Transformer，它在Transformer架构基础上，引入三个独立的领域专家：视觉专家、语言专家和视觉语言专家，以适应和改进多模态处理。
prompt representation learning在论文“learning to prompt for vision-language models”被提出使用的,是第一个在vision-language pretrained model中用prompt learning的,这篇论文提出了CoOp(context optimization)模型。在这篇文章中,作者同样指出,因为设计一个合适的prompt,特别是对于围绕类名的上下文单词,需要该领域的专...
