论文摘要
这项研究评估了脑电图数据的区分能力（唯一性）从脑电图公共数据集的方式彼此对彼此及其持久性进行身份验证的方式。除了脑电图数据外，Luciw等人。提供EMG（肌电图）和运动学数据，以使工程师和研究人员利用eeg Gal进行进一步的研究。但是，评估EMG和运动学数据超出了这项研究的范围。最新的目的是确定是否可以利用脑电图数据来控制假体设备。另一方面，本研究旨在通过脑电图数据来评估个体的可分离性，以执行用户身份验证。功能重要的算法用于选择每个用户的最佳功能，以对其进行对验证。为本研究实施的身份验证平台基于机器学习模型/分类器。作为初始测试，使用线性判别分析（LDA）和支持向量机（SVM）进行了两项试验研究，以通过多标记的EEG数据集观察模型的学习趋势。首先利用KNN作为用户身份验证的分类器，观察到准确性约为75％。此后，用于提高线性和非线性SVM的性能。使用线性和非线性SVM可实现85.18％和86.92％的总体平均精度。除精度外，还计算了F1分数。线性和非线性SVM的总体平均F1得分分别为87.51％和88.94％。除总体表现外，还观察到使用线性SVM和97.4％的精度和97.4％的精度（97.3％F1得分）使用非线性SVM的高表现精度（95.3％F1得分）。
This study evaluates the discriminating capacity (uniqueness) of the EEG data from the WAY EEG GAL public dataset to authenticate individuals against one another as well as its permanence. In addition to the EEG data, Luciw et al. provide EMG (Electromyography), and kinematics data for engineers and researchers to utilize WAY EEG GAL for further studies. However, evaluating the EMG and kinematics data is outside the scope of this study. The goal of the state-of-the-art is to determine whether EEG data can be utilized to control prosthetic devices. On the other hand, this study aims to evaluate the separability of individuals through EEG data to perform user authentication. A feature importance algorithm is utilized to select the best features for each user to authenticate them against all others. The authentication platform implemented for this study is based on Machine Learning models/classifiers. As an initial test, two pilot studies are performed using Linear Discriminant Analysis (LDA) and Support Vector Machine (SVM) to observe the learning trends of the models by multi-labeling the EEG dataset. Utilizing kNN first as the classifier for user authentication, accuracy around 75% is observed. Thereafter to improve the performance both linear and non-linear SVMs are used to perform classification. The overall average accuracies of 85.18% and 86.92% are achieved using linear and non-linear SVMs respectively. In addition to accuracy, F1 scores are also calculated. The overall average F1 score of 87.51% and 88.94% are achieved for linear and non-linear SVMs respectively. Beyond the overall performance, high performing individuals with 95.3% accuracy (95.3% F1 score) using linear SVM and 97.4% accuracy (97.3% F1 score) using non-linear SVM are also observed.
