RT Journal Article T1 Comparing and Tuning Machine Learning Algorithms to Predict Type 2 Diabetes Mellitus A1 Aguilera-Venegas, Gabriel A1 López-Molina, Amador A1 Rojo-Martínez, Gemma A1 Galán-García, José Luis K1 Diabetes K1 Redes neuronales (Informática) K1 Inteligencia artificial AB The main goals of this work are to study and compare machine learning algorithms to predict the development of type 2 diabetes mellitus.Four classification algorithms have been considered, studying and comparing the accuracy of each one to predict the incidence of type 2 diabetes mellitus seven and a half years in advance. Specifically, the techniques studied are: Decision Tree, RandomForest, kNN (k-Nearest Neighbours) and Neural Networks. The study not only involves the comparison among these techniques, but also, the tuning of the hyperparameters of each algorithm.The algorithms have been implemented using the language R. The data base used has been obtained from the nation-wide cohort di@bet.es study. This work includes the accuracy of each algorithm and therefore the best technique for this problem. The best hyperparameters for each algorithm will be also provided.
