Webb8 dec. 2016 · 1 It is not clear from your post whether you want to compute the AUC separately for each of your outputs or not. – nbro Jan 30, 2024 at 1:26 Add a comment 8 Answers Sorted by: 67 Due to that you can't calculate ROC&AUC by mini-batches, you can only calculate it on the end of one epoch. WebbWe used logistic regression analyses to assess predictors of a length of stay above the 75th percentile and assessed the area under the receiving operating characteristic curve to evaluate the model's performance. Results: We included 590 patients (54% women) aged 73.2±10.8 years (mean ± standard deviation) in the analyses.
