Various EEG features have been employed for the implementation of pBCI applications; however, it is frequently reported that some individuals have difficulty fully enjoying the pBCI applications because the dynamic ranges of their EEG features (i.e., its amplitude variability over time) were too small to be used in the practical applications. Conducting preliminary experiments to search for the individualized EEG features associated with different mental states can partly circumvent this issue; however, these time-consuming experiments were not necessary for the majority of users whose dynamic ranges of EEG features are large enough to be used for pBCI applications. In this study, we tried to predict an individual user\u2019s dynamic ranges of the EEG features that are most widely employed for pBCI applications from resting-state EEG (RS-EEG), with the ultimate goal of identifying individuals who might need additional calibration to become suitable for the pBCI applications. We employed a machine learning-based regression model to predict the dynamic ranges of three widely used EEG features known to be associated with the brain states of valence, relaxation, and concentration. Our results showed that the dynamic ranges of EEG features could be predicted with normalized root mean squared errors of 0.2323, 0.1820, and 0.1562, respectively, demonstrating the possibility of predicting the dynamic ranges of the EEG features for pBCI applications using short resting EEG data.<\/jats:p>","DOI":"10.3390\/s20040988","type":"journal-article","created":{"date-parts":[[2020,2,20]],"date-time":"2020-02-20T08:20:03Z","timestamp":1582186803000},"page":"988","source":"Crossref","is-referenced-by-count":5,"title":["Prediction of Individual User\u2019s Dynamic Ranges of EEG Features from Resting-State EEG Data for Evaluating Their Suitability for Passive Brain\u2013Computer Interface Applications"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"http:\/\/orcid.org\/0000-0002-9492-2318","authenticated-orcid":false,"given":"Ho-Seung","family":"Cha","sequence":"first","affiliation":[{"name":"Department of Biomedical Engineering, Hanyang University, Seoul 04763, Korea"}]},{"ORCID":"http:\/\/orcid.org\/0000-0001-8668-3989","authenticated-orcid":false,"given":"Chang-Hee","family":"Han","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Hanyang University, Seoul 04763, Korea"}]},{"ORCID":"http:\/\/orcid.org\/0000-0003-3795-3318","authenticated-orcid":false,"given":"Chang-Hwan","family":"Im","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Hanyang University, Seoul 04763, Korea"}]}],"member":"1968","published-online":{"date-parts":[[2020,2,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"164","DOI":"10.1109\/TRE.2000.847807","article-title":"Brain-computer interface technology: A review of the first international meeting","volume":"8","author":"Wolpaw","year":"2000","journal-title":"IEEE Trans.
