Objective consensus from decision trees
BACKGROUND Consensus-based approaches provide an alternative to evidence-based decision making, especially in situations where high-level evidence is limited. Our aim was to demonstrate a novel source of information, objective consensus based on recommendations in decision tree format from multiple sources. METHODS Based on nine sample recommendations in decision tree format a representative ...
متن کاملEnsembles of Multi-Objective Decision Trees
Ensemble methods are able to improve the predictive performance of many base classifiers. Up till now, they have been applied to classifiers that predict a single target attribute. Given the non-trivial interactions that may occur among the different targets in multi-objective prediction tasks, it is unclear whether ensemble methods also improve the performance in this setting. In this paper, w...
متن کاملConstructing Cost Sensitive Decision Trees Based on Multi-Objective Optimization
We propose a multi-objective optimization based on the cost sensitive decision tree building method. The misclassification cost, test cost, waiting time cost and information gain rate as four optimization goals by using the method of linear weighting are adopted to transfer the multiobjective optimization problem into a single objective optimization problem, as the splitting attribute selection...
متن کاملEmpirical Asymmetric Selective Transfer in Multi-objective Decision Trees
We consider learning tasks where multiple target variables need to be predicted. Two approaches have been used in this setting: (a) build a separate single-target model for each target variable, and (b) build a multi-target model that predicts all targets simultaneously; the latter may exploit potential dependencies among the targets. For a given target, either (a) or (b) can yield the most acc...
متن کاملLexicographic multi-objective evolutionary induction of decision trees
Among the several tasks that evolutionary algorithms have successfully employed, the induction of classification rules and decision trees has been shown to be a relevant approach for several application domains. Decision tree induction algorithms represent one of the most popular techniques for dealing with classification problems. However, conventionally used decision trees induction algorithm...
