The term “Gradient” in Gradient Boosting refers to the fact that you have two or more derivatives of the same function (we’ll cover this in more detail later on). Gradient Boosting is aniterative functional gradient algorithm, i.e an algorithm which minimizes a loss function by iteratively...

Performance The default configuration of AdaBoostM1 is 10 boosting iterations using the DecisionStump classifier. Performance might improve if : 100 iterations were used instead. See below. you kept to 10 iterations but used J48 instead of DecisionStump. Number of iterations With boosting, the...

The Python library provides an implementation of gradient boosting for classification called the GradientBoostingClassifier class and regression called the GradientBoostingRegressor class. It is useful to review the default configuration for the algorithm in this library. There are many parameters, but belo...
The scikit-learn documentation claims that these histogram-based implementations of gradient boosting are orders of magnitude faster than the default gradient boosting implementation provided by the library. These histogram-based estimators can be orders of magnitude faster than GradientBoostingClassifier and...
"GradientBoostedTrees" (Machine Learning Method) Method for Classify and Predict. Predict the value or class of an example using an ensemble of decision trees. Trees are trained sequentially following the boosting meta-algorithm. Gradient boosting is a m
