Fig. 1: Overview of the structure field and crystal structure autoencoder using the NeSF. a The structure field consists of two vector fields, namely, position field fp and species field fs, which are defined in 3D space. Given a 3D point as a query, the position field is trained to ...
Understanding the architecture of autoencoder and its working principal, machine learning practitioners can unlock new possibilities in data analysis and enhance model performance.We have also discussed hyperparameter tuning in autoencoders. Some of the key hyperparameters are learning rate, batch size,...

本次的文章为大家介绍的是自编码器(Autoencoders,简称AE),不同于我们前两次学习的CNN和RNN,自编码器的结构很简单,也没有很独特的单元(例如RNN中的记忆单元)。但是我认为AE的亮点在于它的思想,也就是它使用的“编码-解码”的思想。通常情况下我们使用AE来学习输入的有效表示,同时能够实现降维和提取特征。但是其中...

Autoencoders are a deep learning model for transforming data from a high-dimensional space to a lower-dimensional space. They work by encoding the data, whatever its size, to a 1-D vector. This vector can then be decoded to reconstruct the original data (in this case, an image). The ...
1、auto encoder为什么会提出 对数据过于稀疏而且高维数据难以计算问题的解决 2、auto encoder模型的大致框架 由上图我们可以看出,这是一种无监督模型,通过encoder与decoder两个函数重构形成了新的特征,目标就是最小化重构误差,并用输出去表示输入。 3、auto encoder的前向传播和反向传播算法 4、auto encoder的一些变...
