不严谨地说,该方案突破了以前公知的”contrastive loss不能scaling batch size,显存会炸“的前提,实现了Contrastive Loss 的 batch size 近乎无限的扩展。中国人不骗中国人,以后对比损失实现就用Inf-CL!! 对比学习有多炸不用多说,在图文检索(CLIP为代表),图像自监督学习(SimCLR,MoCo等),文本检索(DPR等)是核心地...
主要的intuition是,clip的目标函数仅使用了跨模态的 contrastive loss,对于单模态内部和跨模态的i2t vst2i的pair的对称性约束稍显不足 loss也很简单,增加了两项 Cross-modal cyclic 约束了当j≠k时, image j(k) 和 text k(j) similarity 的对称性 LC−Cyclic=1N∑j=1N∑k=1N(⟨Ije,Tke⟩−⟨Ik...
这个github(https://github.com/adambielski/siamese-triplet) 中包含了有趣的可视化 Cross-Entropy Loss、Pairwise Ranking Loss 和 Triplet Ranking Loss,它们都基于 MINST 数据集。 Ranking Loss 的其他命名 上文介绍的 Ranking Loss,在许...
Using 64 A100 40GB GPUs, DisCo-CLIP can train the same model with a larger batch size of 196K. We summarize our contributions in twofold. • We propose a novel distributed contrastive loss solu- tion called DisCo for memory efficient CLIP training, which ca...
Contrastive loss has been used recently in a number of papers showing state of the art results with unsupervised learning. MoCo, PIRL, and SimCLR all follow very similar patterns of using a siamese network with contrastive loss. When reading these papers I found that the general idea was very...

We propose a pre-training method called Contrastive Localized Language-Image Pre-training (CLOC) by complementing CLIP with region-text contrastive loss and modules. We formulate a new concept, promptable embeddings, of which the encoder produces image embeddings easy to transform into region ...
Using a contrastive loss, the two networks produce representations of the input images, such that two CoMIRs resulting from corresponding areas in the two input modalities have maximum similarity w.r.t. a selected similarity measure. The networks are provided with randomly chosen \(\{0^{\circ ...
