We marry ideas from deep neural networks and approximate Bayesian inference
to derive a generalised class of deep, directed generative models, endowed with
a new algorithm for scalable inference and learning. Our algorithm introduces a
recognition model to represent approximate posterior distributions, and that
acts as a stochastic encoder of the data. We develop stochastic
back-propagation -- rules for back-propagation through stochastic variables --
and use this to develop an algorithm that allows for joint optimisation of the
parameters of both the generative and recognition model. We demonstrate on
several real-world data sets that the model generates realistic samples,
provides accurate imputations of missing data and is a useful tool for
high-dimensional data visualisation.

本文介绍了一种利用深度神经网络和近似贝叶斯推理相结合的广义深度生成模型，并引入了用于表示近似后验分布的识别模型，并利用随机反向传播来开发算法，实现生成和识别模型参数的联合优化，最终将模型应用于实际数据集，生成更真实的分布、准确地恢复缺失数据，并在高维数据的可视化上发挥了重要作用。
