However, current approaches only consider a limited set of daily activities and do not combine data from individuals. In this work, we propose the use of deep learning techniques to model behavior at the population level and detect significant deviations (i.e., anomalies) while taking into account the whole set of daily activities (41). We detect and visualize daily routine patterns, train a set of recurrent neural networks for behavior modelling with next-day prediction, and model errors with a normal distribution to identify significant deviations while considering the temporal component. Clustering of daily routines achieves a silhouette score of 0.18 and the best model obtains a mean squared error in next day routine prediction of 4.38%. The mean number of deviated activities for the anomalies in the train and test set are 3.6 and 3.0, respectively, with more than 60% of anomalies involving three or more deviated activities in the test set. The methodology is scalable and can incorporate additional activities into the analysis.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Graphical abstract<\/jats:title>\n            <jats:p>A comprehensive activity monitoring and anomaly detection system for older adults, using sensor data, predictive modeling, and statistical analysis to alert health professionals of irregular behaviors.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1007\/s11517-025-03308-y","type":"journal-article","created":{"date-parts":[[2025,1,31]],"date-time":"2025-01-31T14:20:42Z","timestamp":1738333242000},"page":"1821-1835","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Smart home-assisted anomaly detection system for older adults: a deep learning approach with a comprehensive set of daily activities"],"prefix":"10.1007","volume":"63","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7944-2706","authenticated-orcid":false,"given":"Ander","family":"Cejudo","sequence":"first","affiliation":[]},{"given":"Andoni","family":"Beristain","sequence":"additional","affiliation":[]},{"given":"Aitor","family":"Almeida","sequence":"additional","affiliation":[]},{"given":"Kristin","family":"Rebescher","sequence":"additional","affiliation":[]},{"given":"Cristina","family":"Mart\u00edn","sequence":"additional","affiliation":[]},{"given":"Iv\u00e1n","family":"Mac\u00eda","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2025,1,31]]},"reference":[{"key":"3308_CR1","doi-asserted-by":"crossref","unstructured":"Ahsanullah M,\u00a0Kibria BM, Shakil M (2014) Normal distribution.
