Dimensionality Reduction Mappings [PDF]

open access: yes2011 IEEE Symposium on Computational Intelligence and Data Mining (CIDM), 2011
A wealth of powerful dimensionality reduction methods has been established which can be used for data visualization and preprocessing. These are accompanied by formal evaluation schemes, which allow a quantitative evaluation along general principles and ...

Dimensionality Reduction: Challenges and Solutions [PDF]

open access: yesITM Web of Conferences, 2022
The use of dimensionality reduction techniques is a keystone for analyzing and interpreting high dimensional data. These techniques gather several data features of interest, such as dynamical structure, input-output relationships, the correlation between

Non-negative Matrix Factorization for Dimensionality Reduction [PDF]

open access: yesITM Web of Conferences, 2022
—What matrix factorization methods do is reduce the dimensionality of the data without losing any important information. In this work, we present the Non-negative Matrix Factorization (NMF) method, focusing on its advantages concerning other methods of ...

DIMENSIONAL REDUCTION [PDF]

open access: yesModern Physics Letters A, 1999
Using an octonionic formalism, we introduce a new mechanism for reducing ten space–time dimensions to four without compactification. Applying this mechanism to the free, ten-dimensional, massless (momentum space) Dirac equation results in a particle spectrum consisting of exactly three generations.

DIMENSIONAL REDUCTION ON A SPHERE [PDF]

open access: yesInternational Journal of Modern Physics B, 2006
The question of the dimensional reduction of two-dimensional (2d) quantum models on a sphere to one-dimensional (1d) models on a circle is addressed. A possible application is to look at a relation between the 2d anyon model and the 1d Calogero–Sutherland model, which would allow for a better understanding of the connection between 2d anyon exchange ...

Dimensionality reduction of complex dynamical systems

open access: yesiScience, 2021
Summary: One of the outstanding problems in complexity science and engineering is the study of high-dimensional networked systems and of their susceptibility to transitions to undesired states as a result of changes in external drivers or in the ...

Dimensionality reduction methods [PDF]

open access: yesAdvances in Methodology and Statistics, 2005
In case one or more sets of variables are available, the use of dimensional reduction methods could be necessary. In this contest, after a review on the link between the Shrinkage Regression Methods and Dimensional Reduction Methods, authors provide a different multivariate extension of the Garthwaite's PLS approach (1994) where a simple linear ...

Dimensionality reduction using singular vectors

open access: yesScientific Reports, 2021
A common problem in machine learning and pattern recognition is the process of identifying the most relevant features, specifically in dealing with high-dimensional datasets in bioinformatics.

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 ...
