One more thing which is important here is that we are using XGBoost which works based on splitting data using the important feature. A benefit of using ensembles of decision tree methods like gradient boosting is that they can automatically provide estimates of feature importance from a trained predictive model. 1XGBoost 2XGBoost 3() 1XGBoost. The features HouseAge and AveBedrms were not used in any of the splitting rules and thus their importance is 0. Not getting to deep into the ins and outs, RFE is a feature selection method that fits a model and removes the weakest feature (or features) until the specified number of features is reached. The figure shows the significant difference between importance values, given to same features, by different importance metrics. 3- Apply get_dummies() to categorical features which have multiple values (glucose tolerance test, insulin test, age) 2. Well, with the addition of the sparse matrix multiplication feature for Tensor Cores, my algorithm, or other sparse training algorithms, now actually provide speedups of up to 2x during training. According to the dictionary, by far the most important feature is MedInc followed by AveOccup and AveRooms. 2- Apply Label Encoder to categorical features which are binary. When using Univariate with k=3 chisquare you get plas, test, and age as three important features. In fit-time, feature importance can be computed at the end of the training phase. The gradient boosted trees has been around for a while, and there are a lot of materials on the topic. The most important factor behind the success of XGBoost is its scalability in all scenarios.
