Reverse annealing for nonnegative/binary matrix factorization
Fig 2
Calibration of the reverse anneal process.
Evaluated for 100 randomly chosen QUBOs appearing during an evaluation of the NBMF algorithm for with tr = 10μs and tr = 100μs. For a given reversal distance, the height of the green area indicates the mean probability that a reverse anneal sample will have a lower energy than the initial state. The heights of the red and blue areas indicate the mean probability that a given sample will be worse or the same, respectively, as the initial state. Standard deviations, not shown here, were upwards of 100% of the mean, however tr = 10μs and tr = 100μs always behaved similarly, and the peak reversal distance varied little from sample to sample.
