Shape-aware stochastic neighbor embedding for robust data visualisations

open access: yesBMC Bioinformatics, 2022
Background The t-distributed Stochastic Neighbor Embedding (t-SNE) algorithm has emerged as one of the leading methods for visualising high-dimensional (HD) data in a wide variety of fields, especially for revealing cluster structure in HD single-cell ...

Dimensionality reduction in Bayesian estimation algorithms [PDF]

open access: yesAtmospheric Measurement Techniques, 2013
An idealized synthetic database loosely resembling 3-channel passive microwave observations of precipitation against a variable background is employed to examine the performance of a conventional Bayesian retrieval algorithm.

2D Dimensionality Reduction Methods without Loss [PDF]

open access: yesJournal of Artificial Intelligence and Data Mining, 2019
In this paper, several two-dimensional extensions of principal component analysis (PCA) and linear discriminant analysis (LDA) techniques has been applied in a lossless dimensionality reduction framework, for face recognition application.

Supervised dimensionality reduction for big data

open access: yesNature Communications, 2021
Biomedical measurements usually generate high-dimensional data where individual samples are classified in several categories. Vogelstein et al. propose a supervised dimensionality reduction method which estimates the low-dimensional data projection for ...

Analyzing Quality Measurements for Dimensionality Reduction

open access: yesMachine Learning and Knowledge Extraction, 2023
Dimensionality reduction methods can be used to project high-dimensional data into low-dimensional space. If the output space is restricted to two dimensions, the result is a scatter plot whose goal is to present insightful visualizations of distance ...

Haisu: Hierarchically supervised nonlinear dimensionality reduction.

open access: yesPLoS Computational Biology, 2022
We propose a novel strategy for incorporating hierarchical supervised label information into nonlinear dimensionality reduction techniques. Specifically, we extend t-SNE, UMAP, and PHATE to include known or predicted class labels and demonstrate the ...

Dimensionality reduction in neuroscience [PDF]

open access: yesCurrent Biology, 2016
The nervous system extracts information from its environment and distributes and processes that information to inform and drive behaviour. In this task, the nervous system faces a type of data analysis problem, for, while a visual scene may be overflowing with information, reaching for the television remote before us requires extraction of only a ...

An Orthogonal Locality and Globality Dimensionality Reduction Method Based on Twin Eigen Decomposition

open access: yesIEEE Access, 2021
Dimensionality reduction is a hot research topic in pattern recognition. Traditional dimensionality reduction methods can be separated into linear dimensionality reduction methods and nonlinear dimensionality reduction methods.
