Run evaluators on historical observations
Tobias Wochinger
Backfill scores for recent observations when you attach an evaluator to a rule.
You can now run an evaluator on recent historical observations when you attach it to a rule. Enable Also run on past observations to start with scores for existing data while the rule evaluates new observations as they arrive.
Use the backfill to start an online evaluation with scores for observations that arrived before you enabled its rule. For testing an evaluator on selected historical observations or running a one-off evaluation, use batch evaluation.
New evaluator form. Click “Create evaluator”. In the dialog, turn on “Run evaluator on past observations matching these filters”, score the newest 20 matches from the last 30 days and click “Execute”. The Scores page then lists the backfilled scores.
