For their part, neural networks are a family of information-processing techniques capable of approximating highly nonlinear functions. This study proposes to improve the precision in the prediction of air quality. For this purpose, a hybrid adaptation is considered. It is based on an integration of the singular spectrum analysis and the recurrent neural network long short-term memory; the SSA is applied to the original time series to split signal and noise, which are then predicted separately and added together to obtain the final forecasts. This hybrid method provided better performance when compared with other methods.<\/jats:p>","DOI":"10.3390\/e26121062","type":"journal-article","created":{"date-parts":[[2024,12,6]],"date-time":"2024-12-06T09:55:20Z","timestamp":1733478920000},"page":"1062","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Air Quality Prediction Based on Singular Spectrum Analysis and Artificial Neural Networks"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0847-0552","authenticated-orcid":false,"given":"Javier Linkolk","family":"L\u00f3pez-Gonzales","sequence":"first","affiliation":[{"name":"Escuela de Posgrado, Universidad Peruana Uni\u00f3n, Lima 15468, Peru"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0350-6811","authenticated-orcid":false,"given":"Rodrigo","family":"Salas","sequence":"additional","affiliation":[{"name":"Biomedical Engineering School, Faculty of Engineering, Universidad de Valpara\u00edso, Valpara\u00edso 2362905, Chile"},{"name":"Center of Interdisciplinary Biomedical and Engineering Research for Health\u2014MEDING, Universidad de Valpara\u00edso, Valpara\u00edso 2540064, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daira","family":"Velandia","sequence":"additional","affiliation":[{"name":"Statistical Institute, Faculty of Science, Universidad de Valpara\u00edso, Valpara\u00edso 2362905, Chile"},{"name":"Center for Atmospheric Studies and Climate Change\u2014CEACC, Universidad de Valpara\u00edso, Valpara\u00edso 2360102, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1248-9910","authenticated-orcid":false,"given":"Paulo","family":"Canas Rodrigues","sequence":"additional","affiliation":[{"name":"Department of Statistics, Federal University of Bahia, Salvador 40170-110, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,12,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1884","DOI":"10.1016\/j.apr.2019.08.002","article-title":"A hybrid-wavelet model applied for forecasting PM2.5 concentrations in Taiyuan city, China","volume":"10","author":"Wang","year":"2019","journal-title":"Atmos.
