Query: Bayesian Hyperparameter Optimization for Ensemble Learning   In this paper, we bridge the gap between hyperparameter optimization and
ensemble learning by performing Bayesian optimization of an ensemble with
regards to its hyperparameters. Our method consists in building a fixed-size
ensemble, optimizing the configuration of one classifier of the ensemble at
each iteration of the hyperparameter optimization algorithm, taking into
consideration the interaction with the other models when evaluating potential
performances. We also consider the case where the ensemble is to be
reconstructed at the end of the hyperparameter optimization phase, through a
greedy selection over the pool of models generated during the optimization. We
study the performance of our proposed method on three different hyperparameter
spaces, showing that our approach is better than both the best single model and
a greedy ensemble construction over the models produced by a standard Bayesian
optimization.
