Improving classifier decision boundaries and interpretability using nearest neighbors

Abstract Neural networks often fail to learn optimal decision boundaries. In this study, we show that these boundaries are typically situated in regions with low training data density, making them highly sensitive to a small number of samples, which, in turn, increases the risk of overfitting. To ad...
