WebVAE的模型架构上面这张图就是VAE的模型架构,我们先粗略地领会一下这个模型的设计思想。 在auto-encoder中,编码器是直接产生一个编码的,但是在VAE中,为了给编码添加合适的噪音,编码器会输出两个编码,一个是原有编码(m1,m2,m3),另外一个是控制噪音干扰程度的编码(σ1,σ2,σ3),第二个编码其实很 ...
Webcolor perception. Defining a distance between two dis-tributions requires first a notion of distance between the basic features that are aggregated into the distribu-tions. We call this distance the ground distance.For instance, in the case of color, the ground distance mea-sures dissimilarity between individual colors.
