Notes

1. Evaluate uncertainty
   • 1, 2, 3 sigma tests on holdout from 2020 and 2021 data
   • check uncertainty for a slice of data in the high uncertainty zone to see if it is stable or gradually increasing.
2. DECISION: how to use uncertainty?
   • When uncertainty over a threshold project to "closest" point on a spherical map of inputs to uncertainty, and use the GCF/HV setting for the closest point.
3. DECISION: what is the threshold?
   • 0.004
4. DECISION: Which model to use in CPP
   • GPR with learned prior, trained on 2020 and 2021 data.
