Random subsampling in Var Ratios and BALD

[raulsoutelo]

Hi,

In Var Ratios and BALD acquisition functions you first randomly sample a subset (2000 points) of the pool set and then select the points that maximize either Var Ratios or BALD in this subset. Is there any reason for that? Is it only to minimize the acquisition time? Sorry, I have not found any reference to that in the paper.

Thanks!

Hi,

Yes, we subsampled 2000 datapoints at first only because, otherwise it gets computationally expensive to do acquisition over all the data points.

Hope that answers your question.

Thanks, Riashat
