However, most of these methods are designed for specific models. In practice, we often have very little information about the data generating process and different methods can result in very different sets of features. The heterogeneity presented here motivates us to combine various screening methods simultaneously. In this paper, we introduce a general ensemble-based framework to efficiently combine results from multiple variable screening methods. The consistency and sure screening property of proposed framework has been established. Extensive simulation studies confirm our intuition that the proposed ensemble-based method is more robust against model specification than using single variable screening method. The proposed ensemble-based method is used to predict attention deficit hyperactivity disorder (ADHD) status using brain function connectivity (FC).<\/jats:p>","DOI":"10.24963\/ijcai.2019\/501","type":"proceedings-article","created":{"date-parts":[[2019,7,28]],"date-time":"2019-07-28T07:46:05Z","timestamp":1564299965000},"page":"3613-3619","source":"Crossref","is-referenced-by-count":2,"title":["Ensemble-based Ultrahigh-dimensional Variable Screening"],"prefix":"10.24963","author":[{"given":"Wei","family":"Tu","sequence":"first","affiliation":[{"name":"Department of Mathematical and Statistical Sciences, University of Alberta"}]},{"given":"Dong","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Mathematical and Statistical Sciences, University of Alberta"}]},{"given":"Linglong","family":"Kong","sequence":"additional","affiliation":[{"name":"Department of Mathematical and Statistical Sciences, University of Alberta"}]},{"given":"Menglu","family":"Che","sequence":"additional","affiliation":[{"name":"Department of Statistics and Actuarial Science, University of Waterloo"}]},{"given":"Qian","family":"Shi","sequence":"additional","affiliation":[{"name":"Department of Mathematical and Statistical Sciences, University of Alberta"}]},{"given":"Guodong","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Statistics and Actuarial Science, University of Hong Kong"}]},{"given":"Guangjian","family":"Tian","sequence":"additional","affiliation":[{"name":"Huawei Noah\u2019s Ark Lab, Hong Kong, China"}]}],"member":"10584","event":{"number":"28","sponsor":["International Joint Conferences on Artificial Intelligence Organization (IJCAI)"],"acronym":"IJCAI-2019","name":"Twenty-Eighth International Joint Conference on Artificial Intelligence {IJCAI-19}","start":{"date-parts":[[2019,8,10]]},"theme":"Artificial Intelligence","location":"Macao, China","end":{"date-parts":[[2019,8,16]]}},"container-title":["Proceedings of the Twenty-Eighth International Joint Conference on Artificial Intelligence"],"original-title":[],"deposited":{"date-parts":[[2019,7,28]],"date-time":"2019-07-28T07:49:44Z","timestamp":1564300184000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ijcai.org\/proceedings\/2019\/501"}},"subtitle":[],"proceedings-subject":"Artificial Intelligence Research Articles","short-title":[],"issued":{"date-parts":[[2019,8]]},"references-count":0,"URL":"https:\/\/doi.org\/10.24963\/ijcai.2019\/501","relation":{},"subject":[],"published":{"date-parts":[[2019,8]]}}}
