Abstract:Hilbert-Schmidt Independence Criterion (HSIC) has recently been used in the field of single-index models to estimate the directions. Compared with some other well-established methods, it requires relatively weaker conditions. However, its performance has not yet been studied in the high-dimensional scenario, where the number of covariates is much larger than the sample size. In this article, we propose a new efficient sparse estimate in HSIC based single-index model. This new method estimates the subspace span… Show more
