The majority of published papers in the literature focus on single-resident activity recognition. While this is an important area, especially when focusing on elderly people living alone, multi-resident activity recognition has potentially more applications in smart homes. Activity recognition for multiple residents acting concurrently can be treated as a multilabel classification problem (MLC). In this study, an experimental comparison between different MLC algorithms is attempted. Three different techniques were implemented: RAkELd, classifier chains, and binary relevance. These methods are evaluated using the ARAS and CASAS public datasets. Results obtained from experiments have shown that using MLC can recognize activities performed by multiple people with high accuracy. While RAkELd had the best performance, the rest of the methods had on-par results.<\/jats:p>","DOI":"10.3390\/s22062353","type":"journal-article","created":{"date-parts":[[2022,3,20]],"date-time":"2022-03-20T21:37:17Z","timestamp":1647812237000},"page":"2353","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Multilabel Classification Methods for Human Activity Recognition: A Comparison of Algorithms"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1440-1326","authenticated-orcid":false,"given":"Athanasios","family":"Lentzas","sequence":"first","affiliation":[{"name":"Faculty of Sciences, School of Informatics, Aristotle University of Thessaloniki, 541 24 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eleana","family":"Dalagdi","sequence":"additional","affiliation":[{"name":"Faculty of Sciences, School of Informatics, Aristotle University of Thessaloniki, 541 24 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dimitris","family":"Vrakas","sequence":"additional","affiliation":[{"name":"Faculty of Sciences, School of Informatics, Aristotle University of Thessaloniki, 541 24 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"20","DOI":"10.1109\/TITB.2007.899496","article-title":"Detection of Daily Activities and Sports With Wearable Sensors in Controlled and Uncontrolled Conditions","volume":"12","author":"Ermes","year":"2008","journal-title":"IEEE Trans.
