Using Machine Learning to Build an Early Warning Model for the Risk of Severe Airflow Limitation in Patients with Chronic Obstructive Pulmonary Disease
Published 2022-01-01“…A total of 216 prediction models were obtained using 17 machine learning algorithms and 1 integrated learning for each of the 12 datasets. 17 machine learning algorithms with 10-fold cross-validation showed that the differences were statistically significant (P<0.05) when comparing the prediction performance of different algorithms, and the average AUC of the stochastic gradient descent algorithm was maximum (0.738±0.089) . The results of external validation of the test set using the Bootstrapping algorithm showed that the differences were statistically significant (P<0.05) when comparing the prediction performance of the models obtained by different algorithms, and the average AUC of the integrated learning algorithm was maximum (0.757±0.057) . …”
