NettetLong answer for linear as weak learner for boosting: In most cases, we may not use linear learner as a base learner. The reason is simple: adding multiple linear models together will still be a linear model. In boosting our model is a sum of base learners: $$ f(x)=\sum_{m=1}^M b_m(x) $$ Nettet12. jan. 2024 · eval_metric = "rmse", booster = "gbtree") One can choose between decision trees (gbtree and dart) and linear models (gblinear). Unfortunately, there is only limited literature on the comparison of different base learners for boosting (see for example Joshi et al. 2002).

NettetBoosted linear regression. by Marco Taboga, PhD. This lecture introduces a method to train linear regression models where the input is a row vector, the parameter is a vector of regression coefficients and is the prediction of the output . The method is called boosting, and a linear regression model trained with this method is called boosted linear … Nettet16. feb. 2024 · Linear model (such as logistic regression) is not good for boosting. The reason is if you add two linear models together, the result is another linear model. On the other hand, adding two decision stumps or trees, will have a more complicated and interesting model (not a tree any more.) Details can be found in this post.
