Efficient modal regression using gradient ascent and descent method
Ryoya Yamasaki, Toshiyuki Tanaka (Kyoto Univ.) IBISML2017-57
Abstract (in Japanese) (See Japanese page) 
(in English) Nonparametric modal regression is a method for regression analysis, which can estimate local maxima of the conditional probability density function.
In this paper, on the basis of the conditional mean shift, which is a method commonly used for modal regression,we propose a method of estimating local minima of the conditional probability density function.
Furthermore, under the practically important situation where the dependent variable is one-dimensional, we propose an efficient modal regression algorithm by combining the method of estimating local minima with the conditional mean shift.
We experimentally show effectiveness of the proposed method using artificial data as well as real data.
