Deep Bootstrap Aggregation via Least Squares Estimation
Keywords: generalized least squares, bagging, random forest, ensemble learning, regression problems
Abstract: Bootstrap aggregation, commonly referred to as bagging, is a fundamental technique in ensemble learning designed to enhance the performance of predictive models. It is well-established that the effectiveness of bagging is strongly influenced by the management of correlations among the aggregated models. For instance, random forests, a widely-used ensemble method, address this issue by randomly selecting features to reduce the correlation between individual tree models. In this study, we propose a method called ``Deep Bootstrap Aggregation'' for regression tasks, which combines deep network architectures with least squares estimation to improve the predictive accuracy of bagging models. Both theoretical analysis and empirical experiments support the effectiveness of the proposed approach.
