Heavy-Ball-Based Hard Thresholding Pursuit for Sparse Phase Retrieval Problems

open access: yesMathematics, 2023
We introduce a novel iterative algorithm, termed the Heavy-Ball-Based Hard Thresholding Pursuit for sparse phase retrieval problem (SPR-HBHTP), to reconstruct a sparse signal from a small number of magnitude-only measurements.

Kernel conditional quantile estimator under left truncation for functional regressors [PDF]

open access: yesOpuscula Mathematica, 2016
Let \(Y\) be a random real response which is subject to left-truncation by another random variable \(T\). In this paper, we study the kernel conditional quantile estimation when the covariable \(X\) takes values in an infinite-dimensional space. A kernel
