Only a very small portion of the population is able to communicate with the impaired ones. Unfortunately, there aren’t a lot of systems which are available to the public to help in this communication. In this paper we present a component to translate from Portuguese Natural Language to Portuguese Sign Language, using Machine Learning approach, which is a sub-component of a bigger system designed to allow communication between deaf and non-deaf via smartphones. Our approach uses a Neural Machine Translation system to provide translations between Portuguese Natural and Portuguese Sign Language Glosses to be used to animate a 3D avatar. Early testing of different machine learning architectures showed promising results of BiLingual Evaluation Understudy (BLEU) evaluation on translations. The component uses a supervised learning model and results have shown that, under normal operating conditions an accuracy in the detection to translate from Portuguese-to-Portuguese sign language glosses, achieving above 80% on testing data using BLEU performance scores.","PeriodicalId":187896,"journal":{"name":"2022 17th Iberian Conference on Information Systems and Technologies (CISTI)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115980153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A credit card refinancing dataset was used, and results from twotree-based survival analysis tools, Survival Tree and Random Survival Forest, were compared against the usual algorithm based on Cox Proportional Hazards Regression and classification models. The results show that Survival Analysis techniques with tree-based models are good alternatives to traditional survival analysis methods used for PD modeling.","PeriodicalId":187896,"journal":{"name":"2022 17th Iberian Conference on Information Systems and Technologies (CISTI)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115366006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The procedure is validated through metrics and qualitative and quantitative analysis with evaluation indicators on the appropriation or strengthening of emotional skills in children with ASD and the definition of the characteristics of the software developed with co-design techniques that involve the children themselves. The tools considered are non-invasive instruments to collect information, film activities and analyze emotions through the recognition of their facial expressions. Of the main advances achieved, the results of the systematic review of the literature and a case study are presented, where the identification of the most relevant functional and non-functional characteristics of the software applied in the treatment of ASD is obtained, as well as the proposal framework for the design of accessible computer applications focused on users with this cognitive disability.","PeriodicalId":187896,"journal":{"name":"2022 17th Iberian Conference on Information Systems and Technologies (CISTI)","volume":"85 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128792602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
