  • Transaction indicator monitoring methods, apparatuses, and devices
    Patent number: 11455640
    Abstract: A transaction indicator monitoring computer-implemented method, medium, and system are disclosed. One computer-implemented method includes obtaining sampling sequences of a transaction indicator of transaction data under multiple sets of transaction dimension values, each set of transaction dimension values corresponding to one sampling sequence, a first sampling sequence including values of the transaction indicator at a predetermined quantity of sampling points under a first set of transaction dimension values, and a value of the transaction indicator at a target sampling point is a first actual value. An estimated value of the transaction indicator at the target sampling point in the first sampling sequence is calculated based on the first sampling sequence and compared with the first actual value, to determine whether the transaction indicator at the target sampling point under the first set of transaction dimension values corresponding to the first sampling sequence is abnormal.
