An Improved C4.5 Model Classification Algorithm Based on Taylor's Series 基于泰勒级数的改进C4.5模型分类算法

C4.5 is one of the most popular algorithms for rule base classification. Many empirical features in the algorithm exist, such as continuous number categorization, missing value handling and over-fitting. However, despite its promising advantage over the Iterative Dichotomiser 3 (ID3), C4.5 has the major setback of presenting the equivalent result as the ID3, especially when the same number of attributes is used. This paper proposes a technique that will handle the setback reported in C4.5. The performance of the proposed technique is measured based on better accuracy. The Entropy of Information Theory is measured to identify the central attribute for the dataset. The researchers apply exponential splitting information (EC4.5) in utilizing the central attribute of the same dataset. The result obtained on introducing Taylor series suggested a far better result than when the C4.5 (gain ratio) was introduced.
C4.5是最流行的规则库分类算法之一。该算法存在许多经验特征,如连续数分类、缺失值处理和过拟合等。然而,尽管C4.5比迭代二分类器3 (ID3)有很大的优势,但它在表示与ID3相同的结果方面存在很大的缺陷,特别是在使用相同数量的属性时。本文提出了一种处理C4.5中报告的挫折的技术。该技术的性能是基于更好的精度来测量的。通过测量信息熵来确定数据集的中心属性。研究人员利用指数分割信息(EC4.5)来利用同一数据集的中心属性。引入泰勒级数的结果比引入C4.5(增益比)的结果要好得多。

The electroencephalogram (EEG) signal is used as biometric modality, because it is proven to be unique, universal and collectable. This work aims to assess the performance of fuzzy-based techniques for brainprint authentication modelling. We benchmark the performance of Fuzzy-Rough Nearest Neighbour (FRNN) technique to the Discernibility Nearest Neighbour (D-kNN) and the Fuzzy Lattice Reasoning (FLR) techniques using the selected samples of brainwaves’ data from the original UCI EEG dataset. All the three classifiers are available in the fuzzy-rough version of WEKA implementation tool. Selected 9 EEG channels located at the midline and lateral regions were used in the experimentation. The coherence, mean of amplitudes and cross-correlation feature extraction methods were used to extract the EEG signals. The area under ROC curve (AUC) measurement of FRNN was promising against the D-kNN and FLR techniques. The FRNN model has achieved the best performance of AUC measure at 0.904 in opposition to the D-kNN and FLR models, where both recorded 0.770 and 0.563, respectively. However, the classification accuracy shows significantly no difference among the three classifiers. The results confirmed that the classification accuracy of D-kNN and FLR techniques is not reliable, because they are highly contributed by the true negative cases. Hence, we conclude that the FRNN model is less biased to imbalance data problem as compared to the D-kNN and FLR models. Future work of this research should focus on optimizing the EEG channel and feature selection in order to obtain a better data representation of biometric brainprint for more efficient authentication in imbalance data problem.
脑电图(EEG)信号被用作生物识别方式,因为它被证明是独特的、通用的和可收集的。这项工作旨在评估基于模糊的脑印认证建模技术的性能。我们使用从原始UCI EEG数据集中选择的脑电波数据样本,将模糊-粗糙近邻(FRNN)技术的性能与可辨性近邻(D-kNN)和模糊格推理(FLR)技术的性能进行基准测试。所有这三个分类器都可以在WEKA实现工具的模糊粗糙版本中使用。选取位于中线和外侧的9个脑电通道进行实验。采用相干性、幅值均值和互相关特征提取方法提取脑电信号。与D-kNN和FLR技术相比,FRNN的ROC曲线下面积(AUC)测量结果很有希望。与D-kNN和FLR模型相比,FRNN模型在AUC度量方面的最佳性能为0.904,D-kNN和FLR模型分别为0.770和0.563。然而,三种分类器的分类准确率没有显著差异。结果证实了D-kNN和FLR技术的分类精度不可靠,因为它们很大程度上是由真阴性病例贡献的。因此,我们得出结论,与D-kNN和FLR模型相比,FRNN模型对不平衡数据问题的偏差较小。本研究未来的工作重点是优化脑电通道和特征选择,以获得更好的生物特征脑印数据表示,从而在数据不平衡问题下更有效地进行身份验证。
