Adaptive soft contrastive with mutual information for biological time series representation learningThe biotemporal signal dataset is small, and certain signals (electroencephalogram (EEG), electrocardiogram (ECG), and other biological data) used for emotion and disease monitoring vary between individuals. ...
Contrastive representation learning has proven to be an effective self-supervised learning method for images and videos. Most successful approaches are bas
思路很简单,我更愿意称它为(soft self-)supervised contrastive learning,和之前G司的supervised contrastive learning比较类似,只不过标签是online生成的软标签 首先看一张图理解一下 具体实现层面,如图二,主要从FIFO q中挖掘KNN并计算与正样本的相关性,加入损失函数的计算中 ...
很多和soft-label有关的应用都会用到温度T,知识蒸馏会用到T,contrastive learning里面温度T也是很重要的参数。不太一样的地方是在knowledge distillation里面,通常T>1,而在contrastive learning中 MoCo里面T<1。为什么会这样呢? 在计算softmax的时候,T可以调节不同值的“权重”。当T<=1时,标签中最大值的权重会较...
这篇文章算是SimCSE的一个进阶版本吧,关于SimCSE的介绍之前我已经写了一篇小博客(文献阅读:SimCSE:Simple Contrastive Learning of Sentence Embeddings)介绍了一下了,这篇文章感觉像是基于SimCSE之后的一个优化版本。
对比学习 (Contrastive Learning): CLIP 使用对比学习的方式来训练模型。对比学习的目标是将语义上相似的图像和文本嵌入在一个共同的向量空间中,使得相似的图像和文本在这个空间中彼此接近,而不相似的图像和文本则相距较远。 多模态嵌入 (Multimodal Embedding): ...
{SCP}) model for few-shot sentiment analysis. First, we design a sentiment-aware chain of thought prompt module to guide the model to predict the sentiment from coarse grain to fine grain via a series of intermediate reasoning steps. Then, we propose a soft contrastive learning algorithm to ...
Inspired by emotional continuity, SCMM integrates soft contrastive learning with a new hybrid masking strategy to effectively mine the "short-term continuity" characteristics inherent in human emotions. During the self-supervised learning process, soft weights are assigned to sample pairs, enabling ...
