Bat detective—Deep learning tools for bat acoustic signal detection
Fig 4
Comparison of the predicted bat detections (calls and passes) for two different acoustic systems using monitoring data collected from Jersey, UK.
Acoustic systems used were SonoBat (version 3.1.7p) [43] using analysis in [49], and BatDetect CNNFAST using a probability threshold of 0.90. Detections are shown within each box plot, where the black line represents the mean across all transect sampling events from 2011–2015, boxes represent the middle 50% of the data, whiskers represent variability outside the upper and lower quartiles, with outliers plotted as individual points. See text for definition of a bat pass.
