Benchmark datasets with predefined cluster structures and high-dimensional biomedical datasets outline the challenges of cluster analysis: clustering algorithms are limited in their clustering ability in the presence of clusters defining distance-based structures resulting in a biased clustering solution. Data...
this work focuses on non-hierarchical and distance-based clustering. Because clustering can be formulated as a combinatorial optimization problem, several algorithms using Ising machines have been developed28,29,30,31,32,33,34,35

In this paper, we present a distance-based clustering algorithm for grouping database user sessions. The algorithm considers both local and global similarities between sessions and incorporates three distance metrics in the computation of the distance between two sessions. We describe the three metrics...
a consistent use of metric notions.One advantage is the possibility of using concepts and results from the rich literature of metric spaces.Secondly, a mathematically more precise formulation of the problem of clustering will facilitate the discovery of suitable algorithms with well-defined properties....
