Boosted regression tree (BRT) analysis: Optimal parameter settings, predictive performance, and relative influence of environmental variables on total large-bodied reef fish biomass and presence/ab...
These outbreaks are partially regulated by weather parameters such as temperature and precipitation. I use boosted regression tree analysis, applied to a unique dataset including the population density of Mormon crickets (Orthoptera: Tettigoniidae: Anabrus simplex) and modeled weather data, to gain ...
根据处理数据类型的不同,决策树又分为两类:分类决策树与回归决策树,前者可用于处理离散型数据,后者可用于处理连续型数据,下面的英文引用自维基百科。 Classification tree analysis is when the predicted outcome is the class to which the data belongs. Regression tree analysis is when the predicted outcome can...
We have already learned aboutgradient boostinganddecision trees. As a consequence, it will be easy to understand the definition of a boosted tree. A boosted tree is an additive model obtained from a gradient boosting algorithm in which decision trees (or regression trees) are used as base learn...

IBUG computes a non-parametric distribution around a prediction using the $k$-nearest training instances, where distance is measured with a tree-ensemble kernel. The runtime of IBUG depends on the number of training examples at each leaf in the ensemble, and can be improved by sampling trees...
The developed models were constructed based on the boosted regression tree (BRT) and least-squares support vector machine (LSSVM), improved with three metaheuristic algorithms: the gray wolf optimizer (GWO), genetic algorithm (GA), and artificial bee colony (ABC). Six hybrid models, namely BRT...
Boost me up the tree and I'll get the apple.把我托上树,我就能摘到那只苹果了。 They launched a campaign to boost new fashions.他们发起了一项推销新式时装的广告运动。用作名词(n.) Last month saw a tremendous boost in sales.上个月的销售额激增。 This will be a great boost to the econo...
