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...
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 ...
There are many methods such as methods using"Implemented ALOCC for detecting anomalies by deep learning (GAN) - Qiia - kzkadc"and methods using"Detection of Video Anomalies Using Convolutional Autoencoders and One-Class Support Vector Machines (AutoEncoder)"for image anomaly detection using deep ...

In this tutorial we’ll explore the autoencoder architecture and see how we can apply this model to compress images from the MNIST dataset using TensorFlow and Keras. In particular, we’ll consider: Discriminative vs. Generative Modeling
Building a Variational Autoencoder with Keras Now that we understand conceptually how Variational Autoencoders work, let’s get our hands dirty and build a Variational Autoencoder with Keras! Rather than use digits, we’re going to use the Fashion MNIST dataset, which has 28-by-28 grayscale ...
