recommendation systems

Rehearse ranking behavior before rollout.

Determina builds a production-like world around a recommender release so teams can see which candidates move, for which cohort, and why the release needs review.

rank behavior

A cohort lens changes the ranking surface.

Determina replays the release against an enterprise cohort, compares the candidate order before and after the profile merge, then attaches the rank movement to policy evidence.

world to evidence

Candidate-pool conditions become rank evidence.

The rehearsal joins logs, cohort fixtures, profile state, policy thresholds, and the release version into one reviewable ranking run.

Review cohort policy before rollout.

Bring a recommender release to rehearsal.

Start with one ranking change, one cohort that matters, and the policy question your team needs answered before rollout.
