The analysis of these systems using artificial intelligence algorithms helps to improve sustainability and to produce energy efficiently. In this research, a photovoltaic system was analyzed with multiparametric regression models using step-by-step selection techniques such as RFE and SFS adding Shinkrage regularization, thus proposing a hybrid model for the analysis of the 14 independent variables used in this study. The division of the data by cross-validation was 80% for training and 20% for testing, seeds were applied in the randomization of data to obtain a better performance obtaining seed of 8849. The proposed hybrid models RFE-Ridge-Bayesian, RFE -Lasso, and RFE-Ridge discarded the variables: Total energy ',' Daily energy 'and' Irradiance ', while for the proposed hybrid models SFS-Ridge-Bayesian, SFS-Lasso, and SFS-Ridge eliminated:' Frequency ',' Energy daily 'and' Irradiance '. The optimal hyperparameters for the Ridge and Lasso models were also calculated, obtaining alpha values of 1.538 and 0.01 respectively. To validate all the proposed hybrid models, the analysis of linearity, normality of the error terms, non-autocorrelation of the error terms, and homoscedasticity was performed, all models satisfying said validation. The variable to predict with an accuracy of 99.97% in all cases was the active power.","PeriodicalId":265161,"journal":{"name":"International Conference on Advanced Information Science and System","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121637534","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}

This remote helpdesk would also be available \"anytime\" and \"anywhere\" allowing people to be able to resolve issues and questions as soon as possible. The developers decided to develop a web application called University of Santo Tomas Department of Filipino with the purpose to improve the work efficiency and workflow of the department and to allow students to be able to submit and keep track of their submitted documents to the department office. The developers made use of the Waterfall and Agile Hybrid Software Development Life Cycle Methodology to streamline the initial part of the project then develop the system through short development cycles to make improvements during the development phase. To verify if the system would be effective for the Department of Filipino, the developers conducted unit testing, load testing and user acceptance testing for the system. The unit testing yielded results of 87.5% successful test cases for the department chair, 94.4% for the office secretary and 90.4% for the students where the system performed the intended functions with only minor delays and errors. The system was also able to perform its functions even at an increased user load. The admin user acceptance test yielded a score of 81.25 which is an excellent score in the System Usability Scale score scale and 82.825 for the student's test. With this, the system will be greatly beneficial to the work efficiency and workflow of the Department of Filipino office.","PeriodicalId":265161,"journal":{"name":"International Conference on Advanced Information Science and System","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123826546","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}
