无门槛级讲解对比学习中的自监督模型Simsiam - 知乎
论文名称为Exploring Simple Siamese Representation Learning[1]，是大神Kaiming He的团队在表征学习/对比学习/自监督学习问题上提出的新算法。在之前，对比学习（contrastive learning）已经应用于自监督 … 展开
一、模型结构
本文将先给出模型结构的简单阐述，再去用较为通俗易懂的原理解释为什么要这么做。模型的结构图如下图所示：

二、什么是collapsing solutions
依然举一个极端的例子来理解：假设损失函数的最小值为0（即我们要用梯度下降法尽量将损失函数降低到最小值0），那么模型完全可以投机取巧地令所有权重更新为0，这样我们永 … 展开

三、为什么用余弦相似度来做损失函数
我们的任务目标是学习到分布较好的表征向量，什么叫分布较好？也就是相似的向量越接近越好，不相似的向量越远越好。向量远近的度量单位一般可以用向量夹角的大小来表示。… 展开

四、为什么stop-gradient可以解决这个问题
首先，我们先继续用通俗的思路和语言来理解一下为什么stop-gradient可以成功解决collapsing solutions的问题。
由于我们的任务是一个无监督学习任务，即没有target作为 … 展开

What is Siamese contrastive embedding network (Scen)?
We propose a novel formulation to tackle the problem, namely Siamese Contrastive Embedding Network (SCEN), which constructs two independent embedding spaces and utilizes contrastive losses to guide corresponding feature extractors to excavate discriminative prototypes of state and object separately. The overview of our approach is shown in Fig.3.
