An Overview of Variational Autoencoders for Source Separation, Finance, and Bio-Signal Applications

open access: yesEntropy, 2021
Autoencoders are a self-supervised learning system where, during training, the output is an approximation of the input. Typically, autoencoders have three parts: Encoder (which produces a compressed latent space representation of the input data), the ...

FEATURE DESCRIPTOR BY CONVOLUTION AND POOLING AUTOENCODERS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
In this paper we present several descriptors for feature-based matching based on autoencoders, and we evaluate the performance of these descriptors. In a training phase, we learn autoencoders from image patches extracted in local windows surrounding key ...

Improving Large-Scale k-Nearest Neighbor Text Categorization with Label Autoencoders

open access: yesMathematics, 2022
In this paper, we introduce a multi-label lazy learning approach to deal with automatic semantic indexing in large document collections in the presence of complex and structured label vocabularies with high inter-label correlation. The proposed method is
