L1-Penalized Quantile Regression in High-Dimensional Sparse Models We consider median regression and, more generally, a possibly infinite collection of quantile regressions in high-dimensional sparse models. In these model... A Belloni,V Chernozhukov - 《Annals of Statistics》 被引量: 0发表: 2009...

摘要: Recently, the N-way partial least squares (NPLS) approach was reported as an effective tool for neuronal signal decoding and brain-computer interface (BCI) system calibration. This method...关键词: Discrete wavelet transforms genomics smoothing methods wavelet coefficients DOI: 10.1088/1741-...
It relaxes the moment matching requirement of expectation propagation by adding a relaxation factor into the KL minimization. We penalize this relaxation with a l1 penalty. As a result, when two distributions in the relaxed KL divergence are similar, the relaxation factor will be penalized to ze...

L1Packv2 is a Mathematica package that contains a number of algorithms that can be used for the minimization of an ℓ1-penalized least squares functional. The algorithms can handle a mix of penalized and unpenalized variables. Several instructive examples are given. Also, an implementation that...
Concave penalized least squares estimation (PLSE) takes advantage of signal strength to reduce this bias, leading to sharper error bounds in prediction, coefficient estimation and variable selection. For prediction a... L Feng,CH Zhang - 《Annals of Statistics》 被引量: 1发表: 2017年 grpSLOPE...
An algorithm called CausalEQTL,which integrates L0+L1 penalized regression with an ensemble approach to localize eQTL, thereby enhancing prediction performance precisely. - zhc-moushang/CausalEQTL
