The simplest and the most common solution, especially in machine learning domain, is to exclude records with incomplete data. This approach produces datasets with reduced statistical power and can even lead to biased or erroneous final results. There are, however, many proposed imputing methods for missing data. Although some of them, such as multiple imputation, are mature and well researched, they can be prone to misuse and are not always suitable for building complex frameworks. This paper explores neural networks as a potential tool for imputing univariate missing laboratory data during cardiometabolic risk assessment, comparing it to other simple methods that could be easily set up and used further in building predictive models. We have found that neural networks outperform other algorithms for diverse fraction of missing data and different mechanisms causing their missingness.<\/jats:p>","DOI":"10.2298\/csis190710003v","type":"journal-article","created":{"date-parts":[[2020,6,25]],"date-time":"2020-06-25T11:23:03Z","timestamp":1593084183000},"page":"379-401","source":"Crossref","is-referenced-by-count":2,"title":["Missing data imputation in cardiometabolic risk assessment: A solution based on artificial neural networks"],"prefix":"10.2298","volume":"17","author":[{"given":"Dunja","family":"Vrbaski","sequence":"first","affiliation":[{"name":"University of Novi Sad, Faculty of Technical Sciences, Novi Sad, Republic of Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8176-2362","authenticated-orcid":false,"given":"Aleksandar","family":"Kupusinac","sequence":"additional","affiliation":[{"name":"University of Novi Sad, Faculty of Technical Sciences, Novi Sad, Republic of Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rade","family":"Doroslovacki","sequence":"additional","affiliation":[{"name":"University of Novi Sad, Faculty of Technical Sciences, Novi Sad, Republic of Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edita","family":"Stokic","sequence":"additional","affiliation":[{"name":"University of Novi Sad, Faculty of Medicine, Novi Sad, Republic of Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dragan","family":"Ivetic","sequence":"additional","affiliation":[{"name":"University of Novi Sad, Faculty of Technical Sciences, Novi Sad, Republic of Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1078","container-title":["Computer Science and Information Systems"],"original-title":[],"language":"en","deposited":{"date-parts":[[2023,5,29]],"date-time":"2023-05-29T08:05:04Z","timestamp":1685347504000},"score":1,"resource":{"primary":{"URL":"https:\/\/doiserbia.nb.rs\/Article.aspx?ID=1820-02142000003V"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2020]]}},"URL":"https:\/\/doi.org\/10.2298\/csis190710003v","relation":{},"ISSN":["1820-0214","2406-1018"],"issn-type":[{"value":"1820-0214","type":"print"},{"value":"2406-1018","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020]]}}}
