Popis: Machine learning models for classification and segmentation typically use loss functions based on binary or categorical cross entropy (BCE/CCE). Recent work has pointed out that cross entropy is not always optimal for maximizing accuracy of classification models. Instead, power error loss has been suggested as a generalization of BCE employing a power error exponent parameter q that can be adapted to output error distributions. In this paper we apply the power error loss to classification and segmentation using Convolutional Neural Network and a variant of DeepLabV3+. In line with previous findings, classification and segmentation performance can be improved significantly by using an appropriate fixed q. While previous works have found improvements mainly for q>1, here we report also cases where optimal q is
