True positive (TP), control trial false-positive (Control FP), and feeding trial false-positive (FP) detection rates in the test datasets (excluding the training datasets) across sampling rate. Control FP detection rates were found by dividing the number of false-positive detections during control trials by the number of control trials. TP and FP detection rates were found by dividing the numbers of true and false-positive detections during feeding trials by the number of feeding trials. TP, Control FP, and FP detection rates are expressed here as percentages (i.e., multiplied by 100). TP and Control FP detection rates of Nemo’s data using Cali’s detector are labeled ‘Nemo (C)’. Shown are detection rates using (A) the detectors (Fig. 1) optimized for each sea lion, and B) RMS Jerk summed over a 250-ms window with individually optimized thresholds (adjusted from Ydesen et al. [40] to produce detection rates)
