Nonlinear Manifold Learning Integrated with Fully Convolutional Networks for PolSAR Image Classification

open access: yesRemote Sensing, 2020
Synthetic Aperture Rradar (SAR) provides rich ground information for remote sensing survey and can be used all time and in all weather conditions. Polarimetric SAR (PolSAR) can further reveal surface scattering difference and improve radar’s ...

Learning deformable shape manifolds [PDF]

open access: yesPattern Recognition, 2012
We propose an approach to shape detection of highly deformable shapes in images via manifold learning with regression. Our method does not require shape key points be defined at high contrast image regions, nor do we need an initial estimate of the shape. We only require sufficient representative training data and a rough initial estimate of the object

Rolling Element Bearing Fault Diagnosis Using Improved Manifold Learning

open access: yesIEEE Access, 2017
Fault feature can be extracted by traditional manifold learning algorithms, which construct neighborhood graphs by Euclidean distance (ED). It is difficult to get an excellent dimensionality reduction result when processed data has strong correlations ...

Prototype Regularized Manifold Regularization Technique for Semi-Supervised Online Extreme Learning Machine

open access: yesSensors, 2022
Data streaming applications such as the Internet of Things (IoT) require processing or predicting from sequential data from various sensors. However, most of the data are unlabeled, making applying fully supervised learning algorithms impossible.

Perturbing low dimensional activity manifolds in spiking neuronal networks.

open access: yesPLoS Computational Biology, 2019
Several recent studies have shown that neural activity in vivo tends to be constrained to a low-dimensional manifold. Such activity does not arise in simulated neural networks with homogeneous connectivity and it has been suggested that it is indicative ...

Multilabel Learning with Incomplete Using Dual-Manifold Mapping [PDF]

open access: yesJisuanji gongcheng
In multilabel learning, the classification performance can be improved through the effective use of label correlations. However, owing to the subjectivity of manual tagging and the similarity of label semantics in practical applications, an incomplete ...

Tangent space estimation for smooth embeddings of Riemannian manifolds [PDF]

open access: yes, 2012
Numerous dimensionality reduction problems in data analysis involve the recovery of low-dimensional models or the learning of manifolds underlying sets of data. Many manifold learning methods require the estimation of the tangent space of the manifold at

Extendable and invertible manifold learning with geometry regularized autoencoders [PDF]

open access: yes2020 IEEE International Conference on Big Data (Big Data), 2020
A fundamental task in data exploration is to extract simplified low dimensional representations that capture intrinsic geometry in data, especially for faithfully visualizing data in two or three dimensions.
