Fig. 4From: Quantitative prediction of radiographic progression in patients with axial spondyloarthritis using neural network model in a real-world settingArtificial neural network model for mSASSS prediction. A MSE by the number of hidden layers. B ANN-1 with baseline mSASSS as a total score. C ANN-2 with baseline mSASSS as the number of each score. Scatterplots of actual versus predicted mSASSS (left panel) and bar plot of feature importance (right panel). ANN, artificial neural network; MAE, mean absolute error; MSE, mean squared error; RMSE, root mean squared errorBack to article page
