jev-calibrate

smkrv

235

CLI & Pipelines MIT E1 · source linked

Jev is the typed-decision model from TypeSafe: it takes a `state` and a set of questions (`noul`, `choice`, `score`) and returns probabilities instead of text. How well a question works depends on its wording, on your data and on the threshold you cut at, and none of the three can be read off a single good-looking answer.

JEV · Decision point

Jev returns a structured decision for the local program; consult the source for the exact decision policy.

Adds structured choices or scores to the workflow; performance and cost benefits have not been independently verified.
