VTs:考虑到卷积平等地对待每个像素,Visual Transformer(VT)将输入图像的语义概念解耦到不同的channels,然后通过Transformer编码器块将他们关联起来。VT-block包含了三部分。1)一个tokenizer,通过使用一个scaling注意力层来将输入解耦为不同语义的视觉token集。2)一个Trandformer编码器,合并这些视觉tokens的语义信息。3)一...
之前讲过一篇自监督学习:自监督学习(Self Supervised Learning),里面有提到几种把图像转成通用的embedding的方式,有CPC, SimCLR, 还有Moco。今天来详细说一下Moco v3,主要讲下面这篇文章:An Empirical Study of Training Self-Supervised Visual Transformers。 这篇文章主要讲的是自监督ViT的训练技巧。之后一定会讲这...
然后使用离散小波变换 (DWT) 通过将输入\tilde{X}分解为四个小波子带来对其进行下采样,这里采用的是Haar wavelet。具体来说,DWT 沿行应用低通滤波器f_{L} = (1/\sqrt{2},1/\sqrt{2})和高通滤波器f_{H} = (1/\sqrt{2},-1/\sqrt{2}),以将\tilde{X}编码为两个子带X_{L}和X_{H}。接下来,...
