Usage of keys in prototype selection

[hugoych]

Hi,
First of all, thanks a lot for your work and for providing a clear and documented repository associated with your paper!
While reading your paper I wondered how you selected your most orthogonal subset in detail. By looking at the code, I see you provide both keys and queries to the function orthogonal_landmarks. However, it seems you do not use keys to select your subset. Is that an intended behavior?

Thanks !

Hi @hugoych, yes that's right. We experimented with using both, and it performed marginally better, but came at the cost of computational efficiency. Clustering the set of keys and queries was also helpful, but again time inefficient. There may well be a better compromise than what we came up with - let us know if you find one, I'd be very interested!
