Abstract

We propose the Heterogeneity-Stratified Bootstrap (HSBoot), a stratification method that gives higher resampling probabilities to the sample points in the less homogeneous regions. We demonstrate its advantage in the case of training a detector by oversampling the under-represented class in an imbalanced data set. We took a case study of a spoiled food detector in form of an electronic nose. The performance metrics were calculated on the out-of-bag test set as well as on measurements collected from another sensor.
