there is at least 6% increase in F1-score. Table1also shows that the two-step feature selection method gets the highest F1 score. The result illustrates that our two-step feature selection algorithm can efficiently boost the prediction performance with lower computational cost and less risk of ov...
First, the Extreme Gradient Boosting algorithm relies on many hyperparameters to tune during the model building, and the reasonable hyperparameters directly determine the final prediction effect of the model. For the reason that an optimisation algorithm that can balance both data characteristics and ...
