A Hybrid Approach To Hierarchical Density-based Cluster Selection
Claudia Malzer, Marcus Baum
HDBSCAN is a density-based clustering algorithm that constructs a cluster hierarchy tree and then uses a specific stability measure to extract flat clusters from the tree. We show…

Formulas for translative functions
Petra Weidner
In this report, we consider extended real-valued functions on some real vector space. Gerstewitz functionals are used to construct all translative functions. We derive formulas for…

A Unified Approach to Extended Real-Valued Functions
Petra Weidner
Extended real-valued functions are often used in optimization theory, but in different ways for infimum problems and for supremum problems. We present an approach to extended real-…
