XGBoost Linear node
XGBoost Linear© is an advanced implementation of a gradient boosting algorithm with a linear model as the base model. Boosting algorithms iteratively learn weak classifiers and then add them to a final strong classifier. The XGBoost Linear node in Cloud Pak for Data is implemented in Python.
For more information about boosting algorithms, see the XGBoost Tutorials. 1
Note that the XGBoost cross-validation function is not supported in Cloud Pak for Data. You can use the Partition node for this functionality. Also note that XGBoost in Cloud Pak for Data performs one-hot encoding automatically for categorical variables.
