WACERP, built by applying the WAVE voting algorithm to CERP, is an ensemble method designed specially for high-dimensional data sets. Our study used two high-dimensional data sets to investigate the performance of WACERP. The result showed that WACERP consistently outperforms CERP in terms of accuracy, as well as maintaining balance between sensitivity and specificity. WACERP also performs consistently well compared to other popular classification methods. WARF is built by applying WAVE to Random Forest (RF). To evaluate the performance of WARF, we applied WARF, RF and some other widely used classification models to 23 data sets from various areas. Our study showed that WARF performs consistently better than RF and the other classification methods. WARF achieves its best performance at lower ensemble size than RF in general."},{"label":"dcterms.available","value":"2018-03-22T22:39:03Z"},{"label":"dcterms.contributor","value":"Wu, Song"},{"label":"dcterms.creator","value":"Fei, Xiaoke"},{"label":"dcterms.dateAccepted","value":"2018-03-22T22:39:03Z"},{"label":"dcterms.dateSubmitted","value":"2018-03-22T22:39:03Z"},{"label":"dcterms.description","value":"Department of Applied Mathematics and Statistics."},{"label":"dcterms.extent","value":"108 pg."},{"label":"dcterms.format","value":"Application/PDF"},{"label":"dcterms.identifier","value":"http://hdl.handle.net/11401/78126"},{"label":"dcterms.issued","value":"2017-08-01"},{"label":"dcterms.language","value":"en_US"},{"label":"dcterms.provenance","value":"Made available in DSpace on 2018-03-22T22:39:03Z (GMT).
