Ensure diversity sampling instead of random (proportionate) sampling #205
Description
python_mozetl/mozetl/taar/taar_similarity.py
Line 131 in 32d78c3
The diversity of the donor pool is only ensured by the assumption that higher level clustering is substantially diverse. This could be improved by verification of cross-cluster diversity in the addons space.

This also comes back when we specify a proportionate sampling strategy here:
python_mozetl/mozetl/taar/taar_similarity.py
Line 168 in 491fbda
A solution here would be to specify weights that emphasize specific (niche) cluster representation in the final sample without compromising the non-addon diversity of "large" cluster sampling.
Even an inverse of the current strategy could be evaluated.
