SYNOPSIS

DESCRIPTION

Throw every order onto a random-decision-tree obstacle course; the orders that get isolated fastest are the weird ones. No labeled fraud data needed — the algorithm just notices outliers.

"This order — $1,200 from a buyer averaging $40, shipping to a new country, card flagged for prior chargebacks — review before fulfilling."

EXAMPLES

Sakura uses this on every incoming order, quietly. Isolation forests are good at "this point looks unlike the others" without you defining what fraud means. "$1,200 from a buyer who usually spends $40, new country, card has prior chargebacks — review before fulfilling."

FITNESS

Not yet

This method only gives a real answer above a sample threshold. Running it on a small shop produces a confidence band the size of the universe — useless. When the shop crosses the threshold, this lights up.
