AutoEncoder 是 Feedforward Neural Network 的一种,曾经主要用于数据的降维或者特征的抽取,而现在也被扩展用于生成模型中。与其他 Feedforward NN 不同的是,其他 Feedforward NN 关注的是 Output Layer 和错误率,而 AutoEncoder 关注的是 Hidden Layer;其次,普通的 Feedforward NN 一般比较深,而 AutoEncoder 通常...
To generate the PDNN model, noisy sensor data is used as training data input to a deep neural network and training output is valuated with a cost function that incorporates a physics-based model. An autoencoder can be coupled to the PDNN model and trained with the reduced-noise sensor data...

An autoencoder is a neural network that is trained to attempt to copy its input to its output. Definition 2[2] An autoencoder is a type of artificialneural networkused to learn efficient data codings in an unsupervised manner. The aim of an autoencoder is to learn a representation (encodi...
The latent space is computed by a deep autoencoder neural network, with the data to train the network generated in simulation. However, we show that the resulting latent space representation is useful also for learning on a real robot. Our simulation and real-world results demonstrate that by ...

In this paper, we present a deep learning based method for blind hyperspectral unmixing in the form of a neural network autoencoder. We show that the linear mixture model implicitly puts certain architectural constraints on the network, and it effectively performs blind hyperspectral unmixing. Several...
A traditional autoencoder is an unsupervised neural network that learns how to efficiently compress data, which is also called encoding. The autoencoder also learns how to reconstruct the data from the compressed representation such that the difference between the original data and the reconstructed da...
