Fig. 6: Prediction accuracy (Pearson’s r) for four cognitive targets as well as age and sex prediction scores in the HCP-A dataset.

The figure displays results for prediction of cognitive targets using the individual and combined bins strategy (a–d; individual bins are on the diagonal) and the sequential sampling strategy (e–h). Upper and lower boundary of the fill colours indicate the standard deviation across repeats. In addition, results are shown for age prediction (Pearson’s r) and sex classification (balanced accuracy) using the sequential (i, j), individual bins (k, l), and combined bins (m) sampling strategies. Threshold refers to the percentage of highest (HACF) or lowest (LACF) co-fluctuation time points chosen to estimate FC in the sequential sampling strategy and the y-axis displays the prediction scores. In (k, l) the box plot indicates the median (centre line) and the interquartile range. In (m) comparison operators indicate whether scores obtained by a co-fluctuation bin are equivalent to scores obtained by full FC (=) or whether they are less (<) or greater (>) than scores obtained by full FC according to a 5% Bayesian ROPE⁴³. Source data can be obtained from Supplementary Data 2 for plots a–h, and Supplementary Data 3 for plots i–m.
