A QUBO Formulation of the k-Medoids Problem

2019 , Bauckhage, Christian , Piatkowski, Nico , Sifa, Rafet , Hecker, Dirk , Wrobel, Stefan

We are concerned with k-medoids clustering and propose aquadratic unconstrained binary optimization (QUBO) formulation of the problem of identifying k medoids among n data points without having to cluster the data. Given our QUBO formulation of this NP-hard problem, it should be possible to solve it on adiabatic quantum computers.
