StructureToSamples.h File Reference

A little data structure to store a mapping from structures and approx posteriors to posterior samples, using a posterior-weighted reservoir sample. This is mostly a wrapper on a std::map but adds until the number of structures exceeds trim_at, at which point it trims to trim_to by removing the structures with the lowest maximum probability. This lets us store the best performing structures, which are the only ones tht matter in the posterior anyways. More...

Detailed Description

A little data structure to store a mapping from structures and approx posteriors to posterior samples, using a posterior-weighted reservoir sample. This is mostly a wrapper on a std::map but adds until the number of structures exceeds trim_at, at which point it trims to trim_to by removing the structures with the lowest maximum probability. This lets us store the best performing structures, which are the only ones tht matter in the posterior anyways.

NOTE: We learned that we need to map from approx posteriors not just structures since many of the structures are multimodal, so that if we only do it by structure, we end up with bad modes for a structure overwriting the good ones.
