Data Augmentation for Histopathological Images Based on Gaussian-Laplacian Pyramid Blending

no code implementations31 Jan 2020 Steve Tsham Mpinda Ataky, Jonathan de Matos, Alceu de S. Britto Jr., Luiz E. S. Oliveira, Alessandro L. Koerich

Such a problem is troublesome because most of the ML algorithms attempt to optimize a loss function that does not take into account the data imbalance.
