摘要:

在单隐层前向神经网络(SFNN)中,采用三路决策策略构造网络拓扑。然而,该模型具有一般的性能,并且没有考虑工艺成本,因为它具有固定的阈值参数。受序列三路决策(STWD)的启发,本文提出了STWD与SFNN(STWD-SFNN),以提高网络在结构化数据集上的性能。STWD-SFNN采用多粒度层次,由粗到细动态学习隐层节点数,并设置序贯阈值参数。具体而言,在粗粒度层次,STWD-SFNN通过严格的阈值条件处理易分类的实例,在细粒度层次,随着隐层节点数的增加,STWD-SFNN通过宽松的阈值条件处理难分类的实例,从而实现对实例的分类。此外,STWD-SFNN考虑并报告从每个粒度级别产生的过程成本。实验结果表明,STWD-SFNN在结构化数据集上具有比其他SFNN模型更紧凑的网络,并且具有比竞争模型更好的泛化性能。所有模型和数据集都可以从https://github.com/wuc567/Machine-learning/tree/main/STWD-SFNN下载。

英文摘要:

The three-way decisions strategy has been employed to construct network topology in a single hidden layer feedforward neural network (SFNN). However, this model has a general performance, and does not consider the process costs, since it has fixed threshold parameters. Inspired by the sequential three-way decisions (STWD), this paper proposes STWD with an SFNN (STWD-SFNN) to enhance the performance of networks on structured datasets. STWD-SFNN adopts multi-granularity levels to dynamically learn the number of hidden layer nodes from coarse to fine, and set the sequential threshold parameters. Specifically, at the coarse granular level, STWD-SFNN handles easy-to-classify instances by applying strict threshold conditions, and with the increasing number of hidden layer nodes at the fine granular level, STWD-SFNN focuses more on disposing of the difficult-to-classify instances by applying loose threshold conditions, thereby realizing the classification of instances. Moreover, STWD-SFNN considers and reports the process cost produced from each granular level. The experimental results verify that STWD-SFNN has a more compact network on structured datasets than other SFNN models, and has better generalization performance than the competitive models.
