train.csv可称做样本数据(in-sample data)或训练数据,在训练数据中的Survived是目标变量(target variable,即模型的输出变量),其他变量可以称为特征变量(feature,即模型的输入变量)。训练数据用来分析,并训练一个分类模型(Classification Model)。使用分类模型是因为目标变量是类别数据(Categorical Data),即存活和死亡。 t...

Python code, users can load a saved XGBoost or LightGBM model and perform inference on new data up to 36x faster than on a dual 20-core CPU node. Building on the open-source Treelite package, the next version of FIL will add support for scikit-learn and cuML random forest models as ...
However, the downside of this machine learning algorithm is the processing power required to produce the numerous decision trees and compute the predictions depending on the size of the forest, input data, scale of investigation, and desired resolution of output. In addition, as with all ...
Chapter 6 - Other Popular Machine Learning Methods Segment 6 - Ensemble methods with random forest Ensemble Models Ensemble models are machine learning methods that combine several base models to produce one optimal predictive model. They combine decisions from multiple models to improve the overall per...
