Wavelet-based multiresolution data representations for scalable distributed GIS services
… continues to boom. However, currently available data representations for these services are limited by a deficiency of scalability in data formats. In this research, four types of multiresolution data representations based on wavelet theories have been put forward. The designed Wavelet Image …

Operationalizing Cultural Warrant in Knowledge Organization
Data representation of diverse cultures, perspectives, and identities has stepped to the fore in society, especially with the academy’s increasing attention to diversity, equity, and inclusion. The failure to provide descriptions that are inclusive to diverse cultures and perspectives can hinder …

Adversarial Examples and Distribution Shift: A Representations Perspective
… how these perturbations affect the intermediate data representations of the model. Specifically, we compare standard and adversarial representations for models of varying robustness based on a variety of similarity metrics. In fact, we find that it’s possible to detect adversarial examples by …
