Balanced K-means using Quantum annealing

In this paper, we propose a new quantum version of the Balanced K-means algorithm in the D-wave quantum annealer. D-wave 2000Q quantum computer has been used by many papers in the last few years to solve optimization problems and for finding the global minimum of the balanced K-means optimization problem. However, in this paper, we modify the quadratic unconstrained binary optimization (QUBO) formulation of the Balanced K-means that has been proposed in a recent paper. Our modification is trained on different data sets: Iris, Wine and Breast Cancer. Also, we performed a comparative analysis between the two approaches (our approach and the paper's approach) to find the one that assigns the largest number of data to clusters and we also use the Davies-Bouldi metric to prove that our method gives the best clustering.
