Ensemble Method Framework

Ensemble methods can provide more flexible and robust integration of IE models. For clinical note de-identification, we applied a diverse set of classifiers using different types of learning algorithms, including RNN, CRF, MIRA, and SVM. To regulate less accurate outputs from individual classifiers, we have created a voting ensemble that effectively generates more accurate predictions.
