堆叠降噪自动编码器 Stacked Denoising Auto Encoder(SDAE) 自编码器(autoencoder)是神经网络的一种,经过训练后能尝试将输入复制到输出。自编码器内部有一个隐藏层 h,可以产生编码(code)表示输入。该网络可以看作由两部分组成:一个由函数 h = f(x) 表示的编码器和一个生成重构的解码器 r = g(h)。我们不应...
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...
