Binary matrix factorization using D-Wave's quantum annealer

This repo illustrates how to use D-Wave's quantum annealer for computing binary matrix factorization (BMF). This is done via the optimization formulation proposed in the paper

O. A. Malik, H. Ushijima-Mwesigwa, A. Roy, A. Mandal, I. Ghosh. Binary matrix factorization on special purpose hardware. PLOS ONE 16(12): e0261250, 2021. DOI: 10.1371/journal.pone.0261250

Please be aware that the code in this repo is not indended to recreate the results in the paper above. The paper includes a more extensive set of experiments which were run on Fujitu's Digital Annealer.

Some further details on the code

The notebook demo_notebook.ipynb provides a brief introduction to BMF and shows how to run BMF using different D-Wave samplers. In order to use the hybrid and quantum samplers, you will need a D-Wave Leap account. It is straightforward to set up a free trial account at https://cloud.dwavesys.com.
