Figure 6

The performance of the LightGBM model when signals were downsampled to 100 Hz. The numbers without parentheses in the heatmaps indicate the percentage of the scores from human experts (ground truth) that are in agreement with the scores generated by the model. The numbers inside parentheses indicate the percentage of model-generated scores that are in agreement with the scores of the human experts. Therefore, in the left–right diagonal line, the numbers without parentheses indicate recall, and the numbers inside parentheses indicate precision.
