Figure 3

Sensitivity and specificity plot for the global model approach on the PEDESITE dataset, illustrating the impact of the weighting ratio and the choice of window length (1, 2, or 4 s) on the performance of the model. As the weight ratio increases, the model’s sensitivity improves, but at the cost of decreased specificity. Conversely, as the window length increases, the model’s specificity improves, but at the cost of reduced sensitivity. A weight of 1 corresponds to the no-weighting case.
