How the first weeks go
- Fit the data you haveDistributions, regressions, time series: we start with what the system records and say where the data is too thin to decide.
- Put a confidence interval on the decisionA rate, a risk score, a treatment match: each comes with its uncertainty and with the rule that says when a person decides instead.
- Calibrate on a rhythmBack-tests run weekly, drift is reported before anyone asks, and the model version is logged with every output.
In an engagement
A global investment bank scored millions of daily transactions against learned behavioural baselines, every score logged with its inputs and model version1.
What stays
Transaction Anomaly Monitor stays in the book after the engagement. Model and claims reviews run from its numbers, and its evidence is what the regulator sees. Hand-over comes when the number has held for a quarter.
