此外，我们可以看看我们的输出recon_vis.png可视化文件，以查看我们的自动编码器已学会从MNIST数据集正确重建1位数字：图6：使用Keras和TensorFlow训练的深度学习自动编码器重建手写数字。在继续下一节之前，您应该验证autoencoder.model以及images.pickle文件已正确保存到输出目录：下一节将需要这些文件。11使用自动编码器实...
An LSTM Autoencoder is an implementation of an autoencoder for sequence data using an Encoder-Decoder LSTM architecture. Once fit, the encoder part of the model can be used to encode or compress sequence data that in turn may be used in data visualizations or as a feature vector input to ...
Previous part introduced how the ALOCC model for novelty detection works along with some background information about autoencoder and GANs, and in this post, we are going to implement it in Keras.It is recommended to have a general understanding of how the model works before continuing. You ...
