对于autoencoder,自编码器属于无监督学习范畴,通过限定或者约束目标输出值等于输入数据,实现对原始输入信号的自动编码,从特征学习的观点来看,学到的编码也可视为一种对原始输入信号的层次化特征表示。 在代码中,表现为,损失函数的定义上,self.cost = .5*tf.reduce_mean(tf.pow(tf.subtract(self.reconstruction, sel...

1. What is An Autoencoder? An autoencoder is an unsupervised machine-learning algorithm that takes an image as input and reconstructs it using fewer bits. That may sound like image compression, but the biggest difference between an autoencoder and a general purpose image compression algorithm is...
Using our Python code, training with 3,000 pairs of 3D patches for 20 epochs took just 6.2 h on a single GPU (GeForce RTX 3090, Nvidia). The inference process for an image stack composed of 490 × 490 × 300 pixels (partitioned into 75 3D patches) took as few as 8...

This can be easily understood by using thereparameterization trick in variational autoencoders. Referring tothe second equation, we can easily sample imagextfrom a normal distribution as: Here, the epsilonɛis the“noise”term that is randomly sampled from the standard gaussian distribution and is...
