Lesson 05: Feature Importance with XGBoost. Lesson 06: How to Configure Gradient Boosting. Lesson 07: XGBoost Hyperparameter Tuning. This is going to be a lot of fun. You’re going to have to do some work though, a little reading, a little research and a little programming. You want to...
More complex predictive modeling algorithms perform feature importance and selection internally while constructing their model. Some examples include MARS,Random Forestand Gradient Boosted Machines. These models can also report on the variable importance determined during the model preparation pro...

I realised I had seriously underestimated the importance of good footwear by the end of the third day of our walk along the Camino de Santiago. Tucked away somewhere just on the other side of the horizon was the town of Vilalba. The road into the town was the final stretch of a stage ...

This is because the highly correlated features are voted for twice in the model, over inflating their importance. Evaluate the correlation of attributes pairwise with each other using a correlation matrix and remove those features that are the most highly correlated. ...
