除了被视为自动编码器神经网络架构( autoencoder neural network architecture)之外,变分自动编码器(variational autoencoders)还可以在变分贝叶斯方法的数学公式( variational Bayesian methods)中进行研究,通过对应于变分分布参数( probabilistic latent space)的概率隐空间(例如,多元高斯分布)将神经编码器网络连接到其解码器...
autoencoders, Variational autoencoders (VAEs) are generative models, like Generative Adversarial Networks 首先需要明确的是variational autocoder是一种典型的生成模型,而传统的autoencoder则不是。 与经典的autoencoder的不同的是,variational autoencoder通过encoder将input编码为隐空间中的一种分布。 Probabilistic ...

上述经典模型必须依赖于groundtruth annotation，而Generative Model能不一定强依赖于annotation，如给定一个人脸数据集，完全可以不依赖于任何的annotation也可以生成新的人脸，但若希望生成“特殊条件”的人脸，如长头发的人脸，则训练过程依然需要
In this work, two of the most popular deep learning methods, Variational Autoencoder (VAE) and Generative Adversarial Network (GAN), are compared for identifying geological structures using flow and transport data assimilation. Specifically, VAE and GAN are used to re-parameterize the hydraulic ...
Variational AutoEncoder is a type of generative model that applies a probabilistic twist to the encoding process. Instead of producing a single latent code, a variational autoencoder learns a probability distribution over multiple possible latent codes. This approach permits VAE to generate new data ...
Variational autoencoders as a generative model By sampling from the latent space, we can use the decoder network to form a generative model capable of creating new data similar to what was observed during training. Specifically, we'll sample from the prior distribution p(z)p(z) which we ass...
