Early detection could prevent deaths associated to cardiac problems. In this work, we propose a methodology based on data pre-processing and Machine Learning (ML) techniques for predicting cardiovascular disease, by using the Sleep Heart Health Study (SHHS) dataset. First, the principal component analysis and lowest p-value logistic regression are applied to select optimal features which could be related to the CVD. Then, the selected features are used for training four ML algorithms: Naïve Bayes (NB), Feed Forward Neural Networks (NN), Support Vector Machine (SVM) and Random Forest (RF). A binary feature was considered as output of the proposed models and the SMOTE sampling has been used for balancing the training set. Among the proposed methods, NN provided the best accuracy (0.81) and AUC (0.76) outperforming the results obtained in other studies.","PeriodicalId":117157,"journal":{"name":"2020 39th International Conference of the Chilean Computer Science Society (SCCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130137312","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}

It is based on a class of generative learning objects coined by the name boki. It was implemented using the new functionalities offered by Google Sites in a blended learning context. Convergence 3.0 uses the TPACK framework to design learning environments that brings together pedagogical, technological, and content aspects. Specifically, a connectionist learning style is adopted by applying various active learning techniques used in education 3.0. The versatility of the artifact is shown by presenting it as a design pattern adaptable to different contexts in distance education. To illustrate this characteristic, Convergence 3.0 was used to implement a final year course in a computing engineering degree. Finally, some reflections are made based on the experience achieved in recent years using this method, such as the democratization of the classroom and continuous improvement.","PeriodicalId":117157,"journal":{"name":"2020 39th International Conference of the Chilean Computer Science Society (SCCC)","volume":"1918 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130112001","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 solution of sparse triangular linear systems is then one of the fundamental building blocks of numerical methods, which has motivated extensive research dedicated to achieve efficient algorithms for this operation in parallel hardware platforms. However, as it often occurs with sparse problems, the parallel performance of each method depends heavily on the nonzero pattern of the matrix. In this sense, observing these characteristics can allow predicting which method is better suited for each problem.In the case of sparse triangular matrices, one of the most important constrains to parallelism, is the amount of data dependencies during forward or backward substitution. This is related to the number of level-sets, i.e. groups of independent rows in the matrix, but the high cost of computing this number makes its utilization impractical.In this work, we propose different strategies to approximate the number of level-sets through inexpensive procedures, and provide implementations of the heuristics for CPU and GPU.","PeriodicalId":117157,"journal":{"name":"2020 39th International Conference of the Chilean Computer Science Society (SCCC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121714482","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}

Using Agent Based Modeling and Simulation, we study the effects on COVID-19 transmission during a tsunami-threat evacuation in the lockdown of the city of Iquique. Five different scenarios were simulated, considering different amounts of infected agents with capacity to spread the disease, different distribution of agents across the city and two different rates of contagion among agents.
