Minute-wise confusion matrix to estimate the five categories (sleep; sedentary, light, moderate, and vigorous PA) by using optimized thresholds for ROCAM with accelerometry data sampled at 10 Hz. On the right-hand side, we have the percentage of correctly vs. incorrectly matched labels for each of the five categories. Overall accuracy: 80.8%. The results refer to out-of-sample performance and were computed by using the leave-one-participant-out approach, wherein we collated all outputs in a single confusion matrix.
