Species Classification Accuracy using Restricted Mass Ranges.

The species classification accuracy of (a) seven restricted mass ranges were compared. For all restricted mass ranges, the species classification accuracy of high-throughput REIMS out-performed handheld bipolar REIMS. For both REIMS approaches, the restricted mass range of 600 to 1000 m/z provided the highest species classification accuracy. Species classification confusion matrices are shown for (b) handheld bipolar REIMS, and (c) high-throughput REIMS for this restricted mass range. For each colour square, the darkness of blue indicates the level of species classification accuracy, with the darkest colour representing 100% accuracy. Random Forest models constructed on given mass ranges with a mass bin of 0.1 Da and using 400 decision making trees.
