摘要翻译：
脑电图(EEG)作为癫痫发作分类最常用的工具，包含了大脑不同生理状态的有用信息。脑电信号中的癫痫相关特征在时频基预测中可以更好地识别。本文提出了一种新的基于小波包(WPs)的癫痫发作分类方法，该方法通过对母小波函数和小波包基进行后验调整来改进癫痫发作分类。采用支持向量机(SVM)作为分类器，对癫痫发作和非癫痫发作的脑电片段进行分类。为了评价提出的算法，使用了一个公开的数据集，该数据集包含了不同的癫痫患者和健康个体。实验结果表明，本文提出的方法在癫痫发作分类方面优于以前提出的一些算法。

英文摘要：
Electroencephalography (EEG), as the most common tool for epileptic seizure classification, contains useful information about different physiological states of the brain. Seizure related features in EEG signals can be better identified when localized in time frequency basis projections. In this work, a novel method for epileptic seizure classification based on wavelet packets (WPs) is presented in which both mother wavelet function and WP bases are adapted a posteriori to improve the seizure classification. A support vector machine (SVM) as classifier is used for seizure versus non-seizure EEG segment classification. In order to evaluate the proposed algorithm, a publicly available dataset containing different groups patient with epilepsy and healthy individuals are used. The obtained results indicate that the proposed method outperforms some previously proposed algorithms in epileptic seizure classification.
