This trend has allowed for person identification based on behavior rather than physical traits to emerge as a growing research domain, which spans areas such as online education, e-commerce, e-communication, and biometric security. The expression of opinions is an example of online behavior that is commonly shared through the liking of online images. Visual aesthetic is a behavioral biometric that involves using a person\u2019s sense of fondness for images. The identification of individuals using their visual aesthetic values as discriminatory features is an emerging domain of research. This paper introduces a novel method for aesthetic feature dimensionality reduction using gene expression programming. The proposed system is capable of using a tree-based genetic approach for feature recombination. Reducing feature dimensionality improves classifier accuracy, reduces computation runtime, and minimizes required storage. The results obtained on a dataset of 200 Flickr users evaluating 40,000 images demonstrate a 95% accuracy of identity recognition based solely on users\u2019 aesthetic preferences.<\/jats:p>","DOI":"10.3390\/s20041133","type":"journal-article","created":{"date-parts":[[2020,2,20]],"date-time":"2020-02-20T03:20:03Z","timestamp":1582168803000},"page":"1133","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Biometric Identification from Human Aesthetic Preferences"],"prefix":"10.3390","volume":"20","author":[{"given":"Brandon","family":"Sieu","sequence":"first","affiliation":[{"name":"Department of Computer Science, University of Calgary, 2500 University Dr. N.W., Calgary, AB T2N1N4, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marina","family":"Gavrilova","sequence":"additional","affiliation":[{"name":"Department of Computer Science, University of Calgary, 2500 University Dr. N.W., Calgary, AB T2N1N4, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,2,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"496","DOI":"10.3844\/ajassp.2008.496.503","article-title":"Behavioral Modeling: An Overview","volume":"5","author":"Yampolskiy","year":"2008","journal-title":"Am.
