Specifically, tree-based ensemble methods, including bagging, random forest, and gradient boosting, were applied considering their superior performance, and balanced versatility and interpretability. The results revealed that the gradient boosting model produced the most accurate predictions with an R2 ...
Tree-based ensembleVariable selectionLarge amounts of data from high-throughput analytical instruments have generally become more and more complex, bringing a number of challenges to statistical modeling. To understand complex data further, new statistically-efficient approaches are urgently needed to:(1)...
Next, we explore the use of random forests, which generate collections of trees based on bootstrap sampling procedures. We also comment on the tradeoff between the predictive power of ensemble methods and the interpretive value of their single-tree counterparts. The chapter concludes with a ...
Finally, the goal of this contribution is to illuminate the following research question: Do tree-based ensemble methods yield higher accuracy and transparency compared to multilayer perceptrons for the prediction of the added-wave resistance on ships? In this respect, the developed statistical models ...
Tree-based methods 从方法可解释性(interpretation)的角度来说是简单有用的。但是和最先进的有监督算法相比较,性能要差一些。所以这里 我们也介绍了 bagging, random forests, and boosting 等方法,这些方法涉及生成多个树相结合用于产生一个 consensus prediction(少数服从多数的投票)。我们可以看到将大量树组合起来可以...
Our approach is based on constructing a biased tree ensemble, where bias is elaborately designed to recapitulate the prior knowledge of drug targets and their high-confidence biomolecular interactions extracted from the STRING database of molecular interactions29. Tree ensemble methods30,31 such as the...
