The \"sequence detection model\" uses an attention mechanism to assess transaction order, time gaps between actions and device-change patterns, and can spot pauses and resumptions in activity. KakaoBank said prevention cases rose 4.4 times on a monthly average after a pilot. In the first quarter, it detected 49.8 percent of suspected cases independently.
