However, the excessive number of variables with low sample size in the model poses critically challenges to predication accuracy. To enhance the forecasting accuracy and training speed simultaneously, an interpretable model is essential in knowledge recovery. To deal with ultra\u2010high dimensionality, this paper investigates and studies a two\u2010stage procedure to demand sparsity within high\u2010order interaction model. In each stage, square root hard ridge (SRHR) method is applied to discover the relevant variables. The application of square root loss function facilitates the parameter tuning work. On the other hand, hard ridge penalty function is able to handle both the high multicollinearity and selection inconsistency. The real data experiments reveal the superior performances to other comparing approaches.<\/jats:p>","DOI":"10.1155\/2018\/2032987","type":"journal-article","created":{"date-parts":[[2018,11,11]],"date-time":"2018-11-11T23:30:48Z","timestamp":1541979048000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Two\u2010Stage Regularization Method for Variable Selection and Forecasting in High\u2010Order Interaction Model"],"prefix":"10.1155","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4721-4682","authenticated-orcid":false,"given":"Yao","family":"Dong","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6874-9411","authenticated-orcid":false,"given":"He","family":"Jiang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,11,11]]},"reference":[{"key":"e_1_2_10_1_2","first-page":"595","article-title":"Statistical challenges with high dimensionality: Feature selection in knowledge discovery","author":"Fan J.","year":"2006","journal-title":"Proceedings of the International Congress of Mathematicians"},{"key":"e_1_2_10_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.neucom.2017.12.025"},{"key":"e_1_2_10_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.asoc.2017.11.047"},{"key":"e_1_2_10_4_2","doi-asserted-by":"publisher","DOI":"10.1093\/biostatistics\/kxm024"},{"key":"e_1_2_10_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.semcdb.2017.10.016"},{"key":"e_1_2_10_6_2","doi-asserted-by":"publisher","DOI":"10.1109\/TAC.1974.1100705"},{"key":"e_1_2_10_7_2","doi-asserted-by":"publisher","DOI":"10.1214\/aos\/1176344136"},{"key":"e_1_2_10_8_2","doi-asserted-by":"publisher","DOI":"10.1080\/00401706.2000.10485984"},{"key":"e_1_2_10_9_2","doi-asserted-by":"publisher","DOI":"10.1137\/S1064827596304010"},{"key":"e_1_2_10_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijforecast.2012.05.001"},{"key":"e_1_2_10_11_2","doi-asserted-by":"publisher","DOI":"10.1007\/bf03178905"},{"key":"e_1_2_10_12_2","doi-asserted-by":"publisher","DOI":"10.1214\/09-AOS729"},{"key":"e_1_2_10_13_2","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2013.2281303"},{"key":"e_1_2_10_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.knosys.2017.09.041"},{"key":"e_1_2_10_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.amc.2017.01.062"},{"key":"e_1_2_10_16_2","unstructured":"BachF.
