Analysing the interactions between training dataset size, label noise and model performance in remote sensing data

Abstract

In this work we analyse how training datasize affects the ability of a deep neural network to deal with noisy training labels in a semantic segmentation task with labels from OpenStreetMap. To this end, several versions of the training set were created by introducing varying amounts of label noise, and a model was then trained on subsets of varying size of these versions. The results indicate that the relationship between noise level and model performance is largely independent of the datasize except for very small datasizes where adding label noise has an even more deteriorating effect than usual.
