In this paper, the significance of directionality problem has been discussed and is addressed by proposing an ensemble based methodology, which can be used in both classification and regression using chain models, which although mostly competent, possess the issue of a uni-directional dependency.Abstract:
Multi-Target Regression refers to the problem where a set of n independent variables are used to predict the values of k target variables where both k and n are greater than 1. Most methods provide the provision for a regression problem with multiple targets including decision tree regressors and artificial neural networks. However, these methods end up making an assumption that their is no inter-dependency among the target variables. In numerous problems, this assumption turns out to be false which can be notably seen with the variance inflation factor and co-relation of these variables. This consideration was addressed in both classification and regression using chain models, which although mostly competent, possess the issue of a uni-directional dependency. In this work, the significance of directionality problem has been discussed and is addressed by proposing an ensemble based methodology. The comparative analysis of the proposed model is studied against the pre-existing models to explore the improvements in the performance of the model.read more

Variance Inflation Factor: As a Condition for the Inclusion of Suppressor Variable(s) in Regression Analysis
TL;DR: In this article, the authors reviewed several literatures of interest which treat the concept and types of suppressor variables and highlighted systematic ways to identify suppression effect in multiple regressions using statistics such as: R2, sum of squares, regression weight and comparing zero-order correlations with Variance Inflation Factor (VIF) respectively.

Accurate quantitative estimation of energy performance of residential buildings using statistical machine learning tools
TL;DR: In this article, a statistical machine learning framework was developed to study the effect of eight input variables (relative compactness, surface area, wall area, roof area, overall height, orientation, glazing area, etc.) on two output variables, namely heating load (HL) and cooling load (CL), of residential buildings.

TL;DR: The general principle of ensemble methods is to construct a linear combination of some model fitting method, instead of using a single fit of the method.
