Weban integer, the number of iterations for which boosting is run or the number of trees to use. Defaults to mfinal=100 iterations. coeflearn. if 'Breiman' (by default), alpha=1/2ln ( (1-err)/err) is used. If 'Freund' alpha=ln ( (1-err)/err) is used. In both cases the AdaBoost.M1 algorithm is used and alpha is the weight updating coefficient. WebBasic implementation: Implementing regression trees in R. Tuning: Understanding the hyperparameters we can tune. Bagging: Improving performance by fitting many trees. ... In this example, I search a range of minsplit from 5-20 and vary maxdepth from 8-15 (since our original model found an optimal depth of 12).
