The intention of the technique is to benefit from the varying per-formance of Stacking and DI for different data sets, in order to provide a more robust technique. We detail an empirical analysis of the technique referred to as weighted Meta-Combiner (wMetaComb) and compare its per-formance to Stacking and the DI technique of Dynamic Weighting with Selection. The em-pirical analysis consisted of four sets of ex-periments where each experiment recorded the cross-fold evaluation of each technique for a large number of diverse data sets, where each base model is created using random fea-ture selection and the same base learning al-gorithm. Each experiment differed in terms of the latter base learning algorithm used. We demonstrate that for each evaluation, wMeta-Comb was able to outperform DI and Stack-ing for each experiment and as such fuses the two underlying mechanisms successfully","doi":null,"url":"https://ijcai.org/proceedings/2007/457","pdf":"https://ijcai.org/proceedings/2007/0457.pdf","markdown":"https://ijcai.org/proceedings/2007/457.md","bibtex":"https://ijcai.org/proceedings/2007/bibtex/457","volume":{"slug":"2007","title":"Proceedings of the Twentieth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 2007","url":"https://ijcai.org/proceedings/2007/","year":2007,"location":"Hyderabad, India","dates":"","editors":"Ramon López de Mántaras","isbn":"","publisher":"International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":null,"track":"","number":457,"pages":{"first":2844,"last":2848},"keywords":[],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
