PDF Evaluating XGBoost for User Classification by using Behavioral
In this thesis, the focus is primarily on the machine learning aspect of behavioral biometrics, more specifically applying Extreme Gradient Boosting (XGBoost), a gradient boosting approach, to classify users as either genuine or imposters. The impact of XGBoost has been widely recognized in many machine learning and
Tree Boosting With XGBoost
More recently, a tree boosting method known as XGBoost has gained popularity by winning numerous machine learning competitions. In this thesis, we will investigate how XGBoost differs from the more traditional MART. We will show that XGBoost employs a boosting algorithm which we will term Newton boosting. This boosting algorithm will further be ...

[1603.02754] XGBoost: A Scalable Tree Boosting System
Tree boosting is a highly effective and widely used machine learning method. In this paper, we describe a scalable end-to-end tree boosting system called XGBoost, which is used widely by data scientists to achieve state-of-the-art results on many machine learning challenges. We propose a novel sparsity-aware algorithm for sparse data and weighted quantile sketch for approximate tree learning ...

Tree Boosting With XGBoost
The results of the case study show that, overall, XGBoost performs better than AdaBoost and it shows best performance when shallow trees, moderate shrinking, the number of iterations increased with respect to default as well as subsampling of both features and training data points are considered.

TreeBoosting-03: Why Does XGBoost Win Every Machine Learning
XGBoost can thus be seen to be even more adaptive to the data than MART. In addition, XGBoost employs Newton boosting rather than gradient boosting. By doing this, XGBoost is likely to learn better tree structures. Finally, XGBoost includes an extra randomization parameter. This can be used to decorrelate the individual trees even further ...
