Overall strategy and architecture to build our proposed 4-layer DNN model: given the cross-validation accuracy analysis from the best classifier, XGBoost, we modeled with a 4-layer DNN using the top 10 features providing the best cross-validation accuracy. Results of feature importance analysis from XGBoost: SMA is with the highest importance.
