Co je xgboost

Protein intensity data were Z‐scored within cohorts, saved in Excel, and imported via the pandas package (0.25.3). Except for the XGBoost classifier, missing intensities were replaced with 0. Machine learning classifiers were employed using the scikit‐learn package (0.21.3) and the XGBoost package package (0.90) (Fabian et al, 2011

XGBoost je algoritmus, který je založený na gradientních rozhodovacích stromech určených pro rychlost a výkon.XGBoost znamená eXtreme Gradient Boosting. „Název XGBoost však ve skutečnosti odkazuje na inženýrský cíl posunout hranici výpočetních zdrojů pro algoritmy s vylepšeným stromem. XGBoost is a decision-tree-based ensemble Machine Learning algorithm. It uses a gradient boosting framework for solving prediction problems involving unstructured data such as images and text. Gradient boosting is also a popular technique for efficient modeling of tabular datasets. XGBoost is an optimized distributed gradient boosting library designed to be highly efficient, flexible and portable.

Azure Data Science Virtual Machines (DSVMs) have a rich set of tools and libraries for machine learning available in popular languages, such as Python, R, and Julia.

Briefly, XGBoost is a computationally scalable method for generating gradient-boosted models. Also keep in mind that there are two multiclass objectives in xgboost, 'multi:softmax' and 'multi:softprob', producing discrete and probability predictions in different formats. If the developers would agree, it might make sense to start a collection of some reusable custom objective and evaluation functions within the R-package. In a recent problem I've been working on, I found that one feature has 80% importance.

Moje otázka by tedy byla, kdyby někde v dokumentech, které se mi nepodařilo najít, bylo podrobně vysvětleno, co můžeme a nemůžeme použít pro názvy zdrojů Očividně ne. We used the eXtreme Gradient Boosting algorithm, an optimized gradient boosting machine learning library, and established a model to predict events in Philadelphia chromosome-positive acute lymphoblastic leukemia using a machine learning-aided method. A model was constructed using a training set (80%) and prediction was tested using a test set (20%).
