This article covers the mathematics and the fundamental concepts of autoencoders. We will discuss what they are, what the limitations are, the typical use cases, and we will look at some examples. We will start with a general introduction to autoencoders, and we will discuss the role of ...
In this tutorial, we’ll explore how Variational Autoencoders simply but powerfully extend their predecessors, ordinary Autoencoders, to address the challenge of data generation, and then build and train a Variational Autoencoder with Keras to understand and visualize how a VAE learns. Let’s ge...
6.4.2.2.3 Denoising autoencoder Denoising Autoencoders are a variation of autoencoders that were made to fight the inherent bias towards overfitting data that autoencoders can often face. Like sparse autoencoders, the denoising autoencoder tries to fight the possibility of overfitting, but instead...
4.7 Autoencoders An autoencoder is a type of neural network architecture that is having three core components: the encoder, the decoder, and the latent-space representation. The encoder compresses the input to a lower latent-space representation and then the decoder reconstructs it. In NILM, ...
Chapters4and5dive into all the components behind diffusion models and how to get from text to new images. They rely on foundational methods like AutoEncoders—introduced inChapter 3—that can learn efficient representations from input data and reduce the compute requirements to build diffusion and ...
Recent advances in spatially resolved transcriptomics have enabled comprehensive measurements of gene expression patterns while retaining the spatial context of the tissue microenvironment. Deciphering the spatial context of spots in a tissue needs to us

For example, in variational autoencoders, vector quantization has been used to generate images [31], [32] and music [33], [34]. Vector quantization can become prohibitively expensive, as the size of the codebook grows exponentially when rate is increased. For this reason, structured vector ...
An Introduction to Computational Networks and the Computational Network Toolkit Amit Agarwal, Eldar Akchurin, Chris Basoglu, Guoguo Chen, Scott Cyphers, Jasha Droppo, Adam Eversole, Brian Guenter, Mark Hillebrand, Xuedong Huang, Zhiheng Huang, Vladimir Ivanov, Alexey Kamenev, Philipp Kranen, Oleksii...
An autoencoder layer is a component of a neural network that encodes input data into a lower-dimensional representation and then decodes it to reconstruct the original input, identifying hidden semantic features in the process.
