BBBVI took about 3 hours per dataset. The NOMT took less than 5 seconds per dataset. Reviewer 3 noted that the spike-and-slab model does not satisfy the non-overlapping support assumption of Theorem 1. Reviewer 2 pointed out that there is an interesting asymmetry in Theorem 1 with respect to component K. It would be possible to have a "symmetric" version of the theorem, but it would describe a Reviewer 2 suggested using reconstruction error as a metric for the sparse PCA application. I will include a discussion of these similarities and differences in the revision. Reviewer 1 asked if the supports of the mixture distributions must defined a priori.
