Results of the test of the online configuration with penalty. The results of performed tests are reported in terms of the average RMSE (mg/dL). For each patient, we report whether they performed aerobic (AE) or anaerobic (AN) exercise. The second column reports the results referred to the total amount of recorded days, whereas the third refers only to the time stamps during which physical activity (PA) was performed. The average RMSEs are also reported. The bottom panel reports the average RMSE related only to anaerobic and aerobic exercise.
