Julia 6.0 is out with a number of potentially breaking changes. Let's try to bring this code up to speed.

Hi,

Thanks for sharing the code. Recently I am running comparison experiments.

It works well under 64 bits and 128 bits and the results are comparable with LSQ paper. But under 32 bits, the recall is lower than ckmeans. Although LSQ paper didn't have results for 32 bits, can you please check the results for me? Or is there anything I missed?

recalls under 32 bits:
r@1 = 5.09%
r@10 = 23.53%
r@100 = 62.44%

I changed the hyperparameter npert from 4 to 3, 2, and 1, but similar results are obtained.

Thanks,

This seems to be an issue with IterativeSolvers.jl. Probably an update to their port of LSQR.

Writing my thesis and reproducing past results, I realized that this line is wrong:

As using tau = 0.4 for SLSQ2 does not reproduce the results from the ECCV 16 paper.
