WebDec 10, 2015 · The different versions of AUC used in saliency research differ primarily in the nonfixation distribution used. This is usually either a uniformly selected distribution of not-fixated points across the image (e.g., in ref. 25) or the distribution of fixations for other images in the database [the shuffled AUC (3, 4, 39)]. WebAlgorithms were evaluated using shuffled 10-fold cross-validation (CV) and rolling CV. Predictive performance for 1 year and 90 days all-cause mortality was characterized using the area under the receiver-operating characteristic curve (AUC) with 95% confidence interval.
