Damage detection based on the GPR method using (a) temperature and \(\:{f}_{1}\), (b) temperature and \(\:{f}_{2}\) as the input and output, respectively. (The black scatter points represent the prediction errors in the training phase, the blue scatter points represent the undamaged prediction errors in the test phase, and the red points are the damaged prediction errors in the test phase).
