SEMANTIC LANGUAGE FEATURE DEFINITION LANGUAGE FOR USE IN FRAUD DETECTION

Abstract:

A semantic, machine readable language part that supports the specification of features is used by an engine that interprets that language to produce the features based on the raw data. In this way, the model developer can specify the measurement columns (for example, data fields), to obtain the dimensions from which the engine can compute the multiple combinations of features possible based on this set of input fields. This computation of features can be used to perform machine learning (ML) training and/or scoring algorithms (for example, ML algorithms for fraud detection).
