Webb1 juni 2024 · Boosting is an ensemble modeling technique that attempts to build a strong classifier from the number of weak classifiers. It is done by building a model by using weak models in series. Firstly, a model is built from the training data. Then the second model is built which tries to correct the errors present in the first model.

Webb29 aug. 2014 · Boosting is the process of adding weak learners in such a way that newer learners pick up the slack of older learners. In this way we can (hopefully) incrementally increase the accuracy of the model. Using the C5.0()function, we can increase the number of boosting iterations by changing the trialsparameter.
