Classification: CPC H  G | IPC G  H

Claim 14:
15. A non-transitory machine-readable medium having stored thereon machine-readable instructions executable to cause a machine to perform operations comprising:
generating first account data corresponding to a user account, wherein the first account data comprises time series data that corresponds to a first account attribute;
deriving second account data from the first account data, wherein the second account data corresponds to a plurality of account usage frequencies;
determining a plurality of pattern strength values corresponding to the plurality of account usage frequencies based on the second account data, wherein each pattern strength value in the plurality of pattern strength values indicates a corresponding strength of a pattern existing in the first account data according to a corresponding account usage frequency in the plurality of account usage frequencies;
determining (i) a first pattern index based on a first potion of the plurality of pattern strength values that corresponds to a first account usage frequency range and (ii) a second pattern index based on a second portion of the plurality of pattern strength values that corresponds to a second account usage frequency range; and
configuring a decision engine to generate an output indicating a likelihood of anomalous activity associated with the user account using the first pattern index and the second pattern index.
