For tree model Importance type can be defined as: weight: the number of times a feature is used to split the data across all trees. Here we try out the global feature importance calcuations that come with XGBoost. One more thing which is important here is that we are using XGBoost which works based on splitting data using the important feature. According to the dictionary, by far the most important feature is MedInc followed by AveOccup and AveRooms. The Python package is consisted of 3 different interfaces, including native interface, scikit-learn interface and dask interface. Feature Importance is a score assigned to the features of a Machine Learning model that defines how important is a feature to the models prediction.It can help in feature selection and we can get very useful insights about our data. get_score (fmap = '', importance_type = 'weight') Get feature importance of each feature.
