classifier ensemble

Feb 01, 2021 · The dynamic ensemble selection is performed in two variants — on the bagging classifiers level (up to 5 models in the pool) or the level of all base models (up to 50 classifiers in the pool). The variant of dynamic selection is denoted by the number after the name of des method, 1 being bagging classifiers and 2 being all base estimators

    Jun 15, 2019 · Ensemble learning is a way of generating various base classifiers from which a new classifier is derived which performs better than any constituent classifier. These base classifiers may differ in the algorithm used, hyperparameters, representation or the training set. The key objective of the ensemble methods is to reduce bias and variance

    Dynamic classifier selection is a type of ensemble learning algorithm for classification predictive modeling. The technique involves fitting multiple machine learning models on the training dataset, then selecting the model that is expected to perform best when making a prediction, based on the specific details of the example to be predicted. This can be achieved using a k-nearest neighbor model to …

    Feb 01, 2021 · Classifier ensemble selection. In this work, we focus on the last described strategy, specifically on the classifier ensemble selection methods, which employ the overproduce-and-select approach, i.e., we are choosing, based on the local competencies for each sample, which individual models from the pool are used in the classification process. There are two approaches for the …
