Dimensionality Reduction

Dimensionality reduction

Dimensionality reduction is the transformation of data from a high-dimensional space into a low-dimensional space to retain meaningful properties of the original data. It is used in fields with large numbers of observations and/or variables, and can be divided into linear and nonlinear approaches, as well as feature selection and extraction. Dimensionality reduction can be used for noise reduction, data visualization, cluster analysis, or other analyses.
