A Soft Computing Approach for Selecting and Combining Spectral Bands

no code implementations10 Nov 2020 Juan F. H. Albarracín, Rafael S. Oliveira, Marina Hirota, Jefersson A. dos Santos, Ricardo da S. Torres

We introduce a soft computing approach for automatically selecting and combining indices from remote sensing multispectral images that can be used for classification tasks.

Principled Interpolation in Normalizing Flows

no code implementations22 Oct 2020 Samuel G. Fadel, Sebastian Mair, Ricardo da S. Torres, Ulf Brefeld

In this paper, we solve this issue by enforcing a fixed norm and, hence, change the base distribution, to allow for a principled way of interpolation.

Semantic Diversity versus Visual Diversity in Visual Dictionaries

no code implementations20 Nov 2015 Otávio A. B. Penatti, Sandra Avila, Eduardo Valle, Ricardo da S. Torres

Results for image classification show that as visual dictionaries are based on low-level visual appearances, visual diversity is more important than semantic diversity.
