Comparison of parametric and nonparametric ROC confidence bound construction in the context of acoustic/magnetic fusion systems for mine hunting

Traditional Receiver Operating Characteristic (ROC) Curve Confidence Bound Construction Methods are based on the use of asymptotic results or idealized models. In this work, an approach to ROC confidence bound construction is developed for both Per-Token and Cumulative ATR system performance, based on the use of the Bootstrap Method. This technique is nonparametric, and has been applied to problems in which traditional confidence bounds would be difficult, if not impossible, to construct. In addition, the technique is able to encompass the effects of training data and evaluation data variability in a single unified approach. Results are presented contrasting parametric and Bootstrap based cumulative ROC curve confidence bounds for three distinct sets of side-scan sonar data. Finally, Bootstrap based bounds are developed in the context of Acoustic/Magnetic fusion systems.
