Robust projection indices [PDF]

open access: yes, 2001
Loosely speaking a robust projection index is one that prefers projections involving true clusters over projections consisting of a cluster and an outlier.

On Remotest set and Random controls in Kaczmarz algorithm

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2018
In this paper we analyse the Kaczmarz projection algorithm with Remotest set and Random control of projection indices and provide a suficient condition such that each projection index appears infinitely many times during the iterations.

Simultaneous Maximum-Likelihood Reconstruction of Absorption Coefficient, Refractive Index and Dark-Field Scattering Coefficient in X-Ray Talbot-Lau Tomography. [PDF]

open access: yesPLoS ONE, 2016
A maximum-likelihood reconstruction technique for X-ray Talbot-Lau tomography is presented. This technique allows the iterative simultaneous reconstruction of discrete distributions of absorption coefficient, refractive index and a dark-field scattering ...

A single-index quantile regression model and its estimation [PDF]

open access: yes, 2012
Models with single-index structures are among the many existing popular semiparametric approaches for either the conditional mean or the conditional variance. This paper focuses on a single-index model for the conditional quantile. We propose an adaptive

Decision-Making of Irrigation Scheme for Soybeans in the Huaibei Plain Based on Grey Entropy Weight and Grey Relation–Projection Pursuit

open access: yesEntropy, 2019
To provide a scientific reference for formulating an effective soybean irrigation schedule in the Huaibei Plain, potted water deficit experiments with nine alternative irrigation schemes during the 2015 and 2016 seasons were conducted.

Projection pursuit methods for exploratory supervised classification [PDF]

open access: yes, 2003
In high-dimensional data, one often seeks a few interesting low-dimensional projections which reveal important aspects of the data. Projection pursuit is a procedure for searching high-dimensional data for interesting low-dimensional projections via the ...

Estimation of Single-Index Models Based on Boosting Techniques [PDF]

open access: yes, 2008
In single-index models the link or response function is not considered as fixed. The data determine the form of the unknown link function. In order to obtain a flexible form of the link function we specify the link function as an expansion in basis ...

Patterned phosphor-in-glass films with efficient thermal management for high-power laser projection displays

open access: yesJournal of Advanced Ceramics, 2023
Recently, high-performance color converters excitable by blue laser diode (LD) have sprung up for projection displays. However, the thermal accumulation effect of the color converters is a non-negligible problem under high-power LD irradiation.
