Our key innovation is the use of an image-text contrastive learning model to learn coordinated embeddings of image snippets and text descriptions of genes and gene relations, thereby improving curation. Our validation results, using pathway figures from PubMed, showed that our multimodal model ...
2.双编码器对比学习,Dual-Encoder Contrastive Learning: 双编码器方法利用了有噪声的网络规模文本描述,分别用图像encoder和文本encoder提取图像特征和对应的文本特征,通过将正例图文对与采样批次中的其他负例图文对进行对比学习,共同优化两个编码器: \mathcal{L}_{\text{Con}} = -\frac{1}{N} (\underbrace{\...
最近在公司实习,就一直看文献,就在这里总结一下吧~ Contrastive Learning of Medical Visual Representations from Paired Images and Textarxiv.org/abs/2010.00747 这篇文章是20年11月放在arxiv上的,算比较新的文章,现在也有17的引用。 主要讲的多模态学习,如何同时医疗图像和医疗文本(报告)的信息。 模型部分:...

1. 解释什么是Unified Contrastive Learning Unified Contrastive Learning(UniCL)是一种新的学习范式,旨在通过整合图像-标签(Image-Label)和图像-文本(Image-Text)两种数据源,将它们合并到一个共同的图像-文本-标签(Image-Text-Label)空间中,以实现语义丰富且具有辨别力的表征学习。UniCL提出了一个统一的目标函数,以促...

Another distinction is that prior works only use large-scale models pre-trained for image discriminative tasks, e.g., image classification [27, 47] or image-text contrastive learning [30, 41, 53, 57]. The con- current work MaskCLIP [15] also uses CLIP [57...

2021 年 OpenAI 发表的论文《Learning Transferable Visual Models From Natural Language Supervision》提出了 CLIP (Contrastive Language-Image Pre-training) 模型,并在论文中详细阐述了如何通过自然语言处理监督信号,来训练可迁移的视觉模型(其原理架构如下图所示)。
