随着深度学习的发展,自动编码器(Autoencoders)成为了一种重要的无监督学习算法。其中,变分自动编码器(Variational Autoencoders,VAEs)作为一种特殊类型的自动编码器,在生成模型、数据压缩和特征学习等领域取得了很大的成功。本文将介绍变分自动编码器的原理和应用,并探讨其在深度学习中的重要性。
Denoising Autoencoder:The goal is no longer to reconstruct the input data. Rather than adding a penalty to the loss function, we can obtain an autoencoder that learns something useful by changing the reconstruction error term of the loss function. This can be done by adding some noise to the...
Introduction to variational methodsdoi:10.1007/3-540-49541-x_3Variational autoencoders provide a principled framework for learning deep latent-variable models and corresponding inference models. In this work, we provide an introduction to variational autoencoders and some important extensions....
策略框架本质上可看成是agent的大脑, 我们通常可以看到诸如此类的描述,该策略试图最大化奖励(The policy is trying to maximize reward)。 在深度强化学习应用中, 我们通常打交道的对象是参数化策略(parameterized policies),其中策略是由一组参数决定的可计算的函数,比如说由weight和bias参数构成的神经网络模型,我们...
在Variational graph auto-encoders (图变分自编码器)中,将损失函数使用概率描述: P((u,v)\in \varepsilon _g | h_u,h_v) = \sigma (h_u^Th_v) 变分自编码器 VAE[8]:不去关注隐含向量所服从的分布,只需要告诉网络我们想让这个分布转换为什么样子就行了。VAE对隐层的输出增加了长约束,而在对隐...
Variational Autoencoders (VAE):are an improvised version of autoencoders used for learning an optimal latent representation of the input. It consists of an encoder and a decoder with a loss function. VAEs use probabilistic approaches and refers to approximate inference in a latent Gaussian model...
