Besides, sign language represents a direct Human-Computer-Interaction (HCI) similar to voice commands. Therefore, the purpose of this study is to investigate and develop a system for American Sign Language (ASL) alphabet recognition using convolutional neural networks. Our proposal is based on semantic similarity learning using Siamese Convolutional Neural Network to reduce the intra-class variation and inter-class similarity among sign images in a Euclidean space. The results of the siamese architecture applied to the ASL alphabet dataset outperform previous works found in the literature. From these results, using t-SNE visualization, we demonstrate that our hypothesis is correct; the ASL recognition improves when increasing the similarity among encoding of the images belonging to the same class and reducing it otherwise.<\/jats:p>","DOI":"10.3233\/faia210060","type":"book-chapter","created":{"date-parts":[[2021,9,16]],"date-time":"2021-09-16T09:23:08Z","timestamp":1631784188000},"source":"Crossref","is-referenced-by-count":0,"title":["Similarity Learning for CNN-Based ASL Alphabet Recognition"],"prefix":"10.3233","author":[{"given":"Atoany Nazareth","family":"Fierro Radilla","sequence":"first","affiliation":[{"name":"Engineering and Science School, Tecnol\u00f3gico de Monterrey, Cuernavaca, Morelos, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karina Ruby","family":"Perez Daniel","sequence":"additional","affiliation":[{"name":"Engineering and Science School, Tecnol\u00f3gico de Monterrey, Cuernavaca, Morelos, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gibran","family":"Benitez-Garcia","sequence":"additional","affiliation":[{"name":"Graduate School of Informatics and Engineering, The University of Electro-Communications, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pedro","family":"Najera Garcia","sequence":"additional","affiliation":[{"name":"Engineering Faculty, Universidad Panamericana, Mexico City, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ramona","family":"Fuentes Valdez","sequence":"additional","affiliation":[{"name":"Engineering Faculty, Universidad Panamericana, Mexico City, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","New Trends in Intelligent Software Methodologies, Tools and Techniques"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/FAIA210060","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,10,25]],"date-time":"2021-10-25T13:29:36Z","timestamp":1635168576000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/FAIA210060"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,9,8]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/faia210060","relation":{},"ISSN":["0922-6389","1879-8314"],"issn-type":[{"value":"0922-6389","type":"print"},{"value":"1879-8314","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,9,8]]}}}
