Sparse sliced inverse regression for high dimensional data analysis [PDF]

BMC Bioinformatics, 2022
Background Dimension reduction and variable selection play a critical role in the analysis of contemporary high-dimensional data. The semi-parametric multi-index model often serves as a reasonable model for analysis of such high-dimensional data.

Collaborative Sliced Inverse Regression [PDF]

Communications in Statistics - Theory and Methods, 2016
International audienceSliced Inverse Regression (SIR) is an effective method for dimensionality reduction in high-dimensional regression problems. However, the method has requirements on the distribution of the predictors that are hard to check since ...

Student Sliced Inverse Regression [PDF]

Computational Statistics & Data Analysis, 2016
International audienceSliced Inverse Regression (SIR) has been extensively used to reduce the dimension of the predictor space before performing regression. SIR is originally a model free method but it has been shown to actually correspond to the maximum

Sparse Sliced Inverse Regression Via Lasso. [PDF]

J Am Stat Assoc, 2019
For multiple index models, it has recently been shown that the sliced inverse regression (SIR) is consistent for estimating the sufficient dimension reduction (SDR) space if and only if ρ=limpn=0, where p is the dimension and n is the sample size.

A sliced inverse regression (SIR) decoding the forelimb movement from neuronal spikes in the rat motor cortex [PDF]

Frontiers in Neuroscience, 2016
Several neural decoding algorithms have successfully converted brain signals into commands to control a computer cursor and prosthetic devices. A majority of decoding methods, such as population vector algorithms (PVA), optimal linear estimators (OLE ...

Robust Sliced Inverse Regression Procedures [PDF]

, 1998
Sliced Inverse Regression (SIR) is a promising technique for the purpose of dimension reduction. Several properties of this relatively new method have been examined already, but little attention has been paid to robustness aspects.

Entropy-based sliced inverse regression [PDF]

Computational Statistics & Data Analysis, 2013
The importance of dimension reduction has been increasing according to the growth of the size of available data in many fields. An appropriate dimension reduction method of raw data helps to reduce computational time and to expose the intrinsic structure

Kernel Sliced Inverse Regression: Regularization and Consistency [PDF]

Abstract and Applied Analysis, 2013
Kernel sliced inverse regression (KSIR) is a natural framework for nonlinear dimension reduction using the mapping induced by kernels. However, there are numeric, algorithmic, and conceptual subtleties in making the method robust and consistent. We apply
