Encoder基本模块为双卷积形式, 即输入经过两个 ,使用的valid卷积,在代码实现时我们可以增加padding使用same卷积,来适应Skip Architecture。下采样采用的池化层直接缩小2倍。 结构右边是Decoder,即上采样恢复图像尺寸并预测的过程。Decoder一样采用双卷积的形式,其中上采样使用转置卷积实现,每次转置卷积放大2倍。 结构中间co...
The autoencoder architecture consists of two parts: encoder and decoder. Each part consists of 3 Linear layers with ReLU activations. The last activation layer is Sigmoid. The training was done for 120 epochs. Visualizations have been included in the notebook. ...
Autoencoder for sequences of 2D or 3D matrices/images, loosely based on the CNN-LSTM architecture described inBeyond Short Snippets: Deep Networks for Video Classification.Uses a CNN to create vector encodings of each image in an input sequence, and then an LSTM to create encodings of the seq...
Variational Autoencoders (VAEs) allow us to formalize this problem in the framework of probabilistic graphical models where we are maximizing a lower bound on the log likelihood of the data. In this post we will look at a recently developed architecture, Adversarial Autoencoders, which are insp...
