Note that if you specify more than one evaluation metric, all of them will be used for early stopping. This works with both metrics to minimize (L2, log loss, etc.) and to maximize (NDCG, AUC, etc.). Pop art is an art movement that emerged in the United Kingdom and the United States during the mid- to late-1950s. Note that train() will return a model from the best iteration. The index of iteration that has the best performance will be saved in the best_iteration field if early stopping logic is enabled by setting early_stopping callback. Validation score needs to improve at least every stopping_rounds to continue training. The model will train until the validation score stops improving. save_model ( 'model.txt', num_iteration = bst.
