Title: Machine learning-based CT radiomics model for predicting hospital stay in patients with pneumonia associated with SARS-CoV-2 infection: A multicenter study Document date: 2020_3_3
ID: 2s4ifz7i_27
Snippet: In total, 1218 features were calculated per lesion patch. First-order, shape and second-order features were extracted from original images and wavelet filter applied images using pyradiomics. 10 Two supervised learning algorithms, logistic regression (LR) and random forest (RF), were used to build the model and verify the robustness of features (supplementary file). 11 We applied 5-fold cross-validation on the training dataset to prove model perf.....
