A study of tree-based methods and their combination

Tree-based methods are popular machine learning techniques used in various fields. In this work, we review their foundations and a general framework the importance sampled learning ensemble (ISLE) that accelerates their fitting process. Furthermore, we describe a model combination strategy called the adaptive regression by mixing (ARM), which is feasible for tree- based methods via ISLE. Moreover, three modified ISLEs are proposed, and their performance are evaluated on the real data sets.
