There are several modifications to the standard FAO Penman-Monteith equation (PM) that enables us to use limited climatic data for estimating ET0, however these equations have to be adjusted locally depending of the different climatic conditions. In this paper, we use Bayesian model averaging in order to determine the uncertainty of different models that explain ET0. Using this approach, we tackle the multi-collinearity problem of climatic variables by combining multiple regression models. More specifically, we consider estimation of ET0, as a non-stationary regression problem where the rules governing the mean and noise processes might change depending of the different climatic conditions. In order to build the candidate models, we use a divide and conquer approach known as Treed Gaussian Processes (TGP) and then demonstrate the method by using time series of ET0 calculated by means of the PM, equation. The results are also compared with other regression techniques and simplified equations for calculating ET0.","PeriodicalId":131364,"journal":{"name":"2011 UKSim 5th European Symposium on Computer Modeling and Simulation","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114063471","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}

Ebrahim","doi":"10.1109/EMS.2011.27","DOIUrl":"https://doi.org/10.1109/EMS.2011.27","url":null,"abstract":"Evaluating learners in terms of collaboration capabilities in a collaborative e-learning session can be quantified based on several parameters. These parameters include learner's contribution in the collaborative e-learning session. They also include learner's collaboration history in collaborative e-learning sessions and the collaboration capabilities of the group in which he participates. These parameters can be used as inputs to a model that generates a set of recommendations for the next step that should be taken towards the e-learning objectives. These recommendations can be used to enroll the learner in an e-learning session that best fits his collaboration capabilities. In this paper, a fuzzy inference system is introduced to estimate learner's collaboration in terms of a proposed metric called collaboration-index. This index can be utilized to guide the e-learning system for advising the learner to the best choice of the next collaborative e-learning session. Simulation study has been carried out to evaluate the performance of the proposed strategy. Simulation results show that the proposed strategy provides a positive impact on collaborative e-learning environments.","PeriodicalId":131364,"journal":{"name":"2011 UKSim 5th European Symposium on Computer Modeling and Simulation","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121463609","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}
