Currently, the main issue preventing effective translation models lays in the low availability of labelled data, which hinders the use of modern deep learning models.\r\n\r\n\r\nSLT is a complex problem that involves many subtasks, of which handshape recognition is the most important. We compare a series of models specially tailored for small datasets to improve their performance on handshape recognition tasks. We evaluate Wide-DenseNet and few-shot Prototypical Network models with and without transfer learning, and also using Model-Agnostic Meta-Learning (MAML).\r\n\r\nOur findings indicate that Wide-DenseNet without transfer learning and Prototipical Networks with transfer learning provide the best results. Prototypical networks, particularly, are vastly superior when using less than 30 samples, while Wide-DenseNet achieves the best results with more samples. On the other hand, MAML does not improve performance in any scenario. These results can help to design better SLT models.","url_abs":"https://journal.info.unlp.edu.ar/JCST/article/view/2297","url_pdf":"https://journal.info.unlp.edu.ar/JCST/article/view/2297/1667","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"a-comparison-of-small-sample-methods-for","repo_url":"https://github.com/midusi/cacic2019-handshapes","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":0,"framework":"tf","reach":{"status":"ok","spdx":"AGPL-3.0"}}],"tasks":[{"task_slug":"hand-gesture-recognition","task_name":"Hand Gesture Recognition"},{"task_slug":"meta-learning","task_name":"Meta-Learning"},{"task_slug":"sign-language-translation","task_name":"Sign Language Translation"},{"task_slug":"transfer-learning","task_name":"Transfer Learning"},{"task_slug":"translation","task_name":"Translation"}],"methods":[{"method_slug":"maml","method_name":"MAML"}],"datasets_introduced":[],"methods_introduced":[],"results":[{"leaderboard":"/sota/hand-gesture-recognition-on-lsa16","task":"Hand Gesture Recognition","dataset":"LSA16","model":"Prototypical Networks + CNN","rank_in_archive_order":1,"of":3,"metrics":{"Accuracy ":"98.38"},"uses_additional_data":false},{"leaderboard":"/sota/hand-gesture-recognition-on-rwth-phoenix","task":"Hand Gesture Recognition","dataset":"RWTH-PHOENIX Handshapes dev set","model":"DenseNet","rank_in_archive_order":1,"of":2,"metrics":{"Accuracy ":"96.05"},"uses_additional_data":false}],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
