Neural network ensembles Abstract: Several means for improving the performance and training of neural networks for classification are proposed. Crossvalidation is used as a tool for optimizing network parameters and architecture.

Feb 1, 2023 · Ensemble learning based on deep learning models is more difficult than ensemble learning based on traditional classifiers due to deep neural networks containing millions to billions of hyper-parameters that need a lot of time and space to train multiple base deep learners.

Sep 29, 2021 · The right balance of learner accuracy and ensemble diversity can improve the performance of machine learning tasks on benchmark and real-world data sets, and recent theoretical and practical work has demonstrated the subtle trade-off between accuracy and diversity in an ensemble.

Apr 6, 2021 · This paper reviews the state-of-art deep ensemble models and hence serves as an extensive summary for the researchers. The ensemble models are broadly categorised into bagging, boosting, stacking, negative correlation based deep ensemble models, explicit/implicit ensembles, homogeneous/heterogeneous ensemble, decision fusion strategies based ...

Jan 23, 2025 · Ensemble learning combines the predictions of multiple models (called "weak learners" or "base models") to make a stronger, more reliable prediction. The goal is to reduce errors and improve performance. It is like asking a group of experts for their opinions instead of relying on just one person.

Aug 28, 2020 · Model averaging is an ensemble learning technique that reduces the variance in a final neural network model, sacrificing spread in the performance of the model for a confidence in what performance to expect from the model. In this tutorial, you will discover how to develop a model averaging ensemble in Keras to reduce the variance in a final model.

Aug 6, 2019 · Ensemble learning combines the predictions from multiple neural network models to reduce the variance of predictions and reduce generalization error. Techniques for ensemble learning can be grouped by the element that is varied, such as training data, the model, and how predictions are combined.

May 1, 2002 · In this paper, the relationship between the ensemble and its component neural networks is analyzed from the context of both regression and classification, which reveals that it may be better to ensemble many instead of all of the neural networks at hand.

Jul 1, 2020 · In this post, we apply the ensemble mechanism in the neural network domain. More precisely we present various ways to combine deep learning structures efficiently. We make an example in the image classification domain where it is common to meet very deep models.

In this tutorial, you will discover how to develop a stacked generalization ensemble for deep learning neural networks. After completing this tutorial, you will know: Stacked generalization is an ensemble method where a new model learns how to best combine the predictions from multiple existing models.
