Ensemble methods are commonly used in classification due to their remarkable performance. Achieving high accuracy in a data stream environment is a challenging task considering disruptive changes in the data distribution, also known as concept drift. A greater diversity of ensemble components is known to enhance prediction accuracy in such settings. Despite the diversity of components within an ensemble, not all contribute as expected to its overall performance. This necessitates a method for selecting components that exhibit high performance and diversity. We present a novel ensemble construction and maintenance approach based on MMR (Maximal Marginal Relevance) that dynamically combines the diversity and prediction accuracy of components during the process of structuring an ensemble. The experimental results on both four real and 11 synthetic datasets demonstrate that the proposed approach (DynED) provides a higher average mean accuracy compared to the five state-of-the-art baselines.

提出了一种基于最大边际相关性（Maximal Marginal Relevance）的全新集成构建和维护方法（DynED），该方法在构建集成的过程中动态地将组件的多样性和预测准确性进行结合，实验结果表明，与五种最新方法相比，该方法在四个真实和11个合成数据集上提供了更高的平均准确度。
