Many have shown high accuracy in PD classification using machine learning (ML) and voice records from the mPower study, a large database of PD patients and healthy controls. Since the dataset has unbalanced class, gender and age distribution, it is important to consider appropriate sampling when assessing classification scores. We analyse biases, such as identity confounding and implicit learning of non-disease-specific characteristics and present a sampling strategy to highlight and prevent these problems.<\/jats:p>","DOI":"10.3233\/shti230079","type":"book-chapter","created":{"date-parts":[[2023,5,19]],"date-time":"2023-05-19T08:43:02Z","timestamp":1684485782000},"source":"Crossref","is-referenced-by-count":1,"title":["Classification of Parkinson\u2019s Disease from Voice \u2013 Analysis of Data Selection Bias"],"prefix":"10.3233","author":[{"given":"Alexander","family":"Brenner","sequence":"first","affiliation":[{"name":"Institute of Medical Informatics, University of M\u00fcnster, M\u00fcnster, Germany"}]},{"given":"Catharina Marie","family":"Van Alen","sequence":"additional","affiliation":[{"name":"Institute of Medical Informatics, University of M\u00fcnster, M\u00fcnster, Germany"}]},{"given":"Lucas","family":"Plagwitz","sequence":"additional","affiliation":[{"name":"Institute of Medical Informatics, University of M\u00fcnster, M\u00fcnster, Germany"}]},{"given":"Julian","family":"Varghese","sequence":"additional","affiliation":[{"name":"Institute of Medical Informatics, University of M\u00fcnster, M\u00fcnster, Germany"}]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","Caring is Sharing \u2013 Exploiting the Value in Data for Health and Innovation"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/SHTI230079","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,5,31]],"date-time":"2023-05-31T14:56:06Z","timestamp":1685544966000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/SHTI230079"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,5,18]]},"ISBN":["9781643683881","9781643683898"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/shti230079","relation":{},"ISSN":["0926-9630","1879-8365"],"issn-type":[{"value":"0926-9630","type":"print"},{"value":"1879-8365","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,5,18]]}}}
