作者使用Caffe架构实现了上述想法,其源代码位于:GitHub - cdoersch/vae_tutorial: Caffe code to accompany my Tutorial on Variational Autoencoders 4.1 MNIST变分自编码器 为了展示所述框架的分布学习能力,让我们在MNIST上从头开始训练一个变分自编码器。为了证明该框架不严重依赖初始化或者网络结构,我们不使用现存的...
本文理论部分基本译自 Tutorial on Variational Autoencoders by Carl Doersch 1. 介绍 “生成模型”是指能够通过定义在高维空间 X 的数据 X 的概率分布 P(X) 随机生成观测数据的模型。举例来说,对于一幅图片,生成模型的工作就是捕获图像中像素点之间的关系并通过这种关系生成新的目标。最为直接的办法就是通过数...

To address these issues, we developed an open-source machine learning model, Joint Variational Autoencoders for multimodal Imputation and Embedding (JAMIE). JAMIE takes single-cell multimodal data that can have partially matched samples across modalities. Variational autoencoders learn the latent ...
In particular, it provides the possibility to perform benchmark experiments and comparisons by training the models with the same autoencoding neural network architecture. The feature make your own autoencoder allows you to train any of these models with your own data and own Encoder and Decoder ...
For an excellent overview of VAEs we refer the reader to the tutorial of Doersch [8] as we here only outline the core idea. VAEs learn to map data samples X to a posterior distribution Q(z | X) rather than a deterministic latent representation as used in conventional autoencoders. ...
