Random model trees: an effective and scalable regression method

open access: yes, 2010
We present and investigate ensembles of randomized model trees as a novel regression method. Such ensembles combine the scalability of tree-based methods with predictive performance rivaling the state of the art in numeric prediction.

Estimation in multiple regression model with elliptically contoured errors under MLINEX loss [PDF]

open access: yes, 2008
This paper considers estimation of the regression vector of the multiple regression model with elliptically symmetric contoured errors. The generalized least square (GLS), restricted GLS and preliminary test (PT) estimators for regression parameter ...

Classification and Evaluation of Quality Grades of Organic Green Teas Using an Electronic Nose Based on Machine Learning Algorithms

open access: yesIEEE Access, 2019
The quality grades of organic green teas are tightly correlated with their prices. In this work, samples of organic green teas of different quality grades are collected, and their aromas are analyzed with an electronic nose (E-nose).

NATIONAL AND REGIONAL COORDINATES OF THE REAL CONVERGENCE PROCESS INTENSITY IN THE ENLARGED EUROPEAN UNION [PDF]

open access: yesCES Working Papers, 2012
Real convergence of EU economies can be approached from the perspective of close relations between the state of homogeneity and the existence of conditions that can facilitate it. In this paper we test the hypothesis of beta convergence at national level
