Abstract: The disclosed fraud risk scoring tool provides data-driven identification of potential fraud cases. A fraud risk score is determined based at least on a weighted sum of multiple metrics, where weights are determined based on precision or inverse variance and suspension propensity importance, which is indicative of variable importance. An exemplary method includes: receiving and aggregating transaction metrics across customer IDs to produce an aggregated transaction metric data set; determining, for each aggregated transaction metric in the aggregated transaction metric data set, a precision value, a suspension propensity importance, and a scoring weight based at least on one of the precision value and the suspension propensity importance; determining, for each customer ID within the plurality of customer IDs, a risk score based at least on the scoring weights applied to corresponding transaction metrics and a risk priority; and reporting at least one customer ID associated with a selected risk priority.

Abstract: Various embodiments include a classification platform system. A user can define a classification experiment on the classification platform system. For example, the user can define an input data space by selecting at least one of data sources interfaced with the classification platform system and defining a workflow configuration including a directed graph (DG) connecting a plurality of transformation blocks to represent an experiment workflow. The DG can specify how one or more outputs of each of the transformation blocks are fed into one or more other transformation blocks. The DG can be executed by various types of computation platforms. The classification platform system can schedule the experiment workflow to be executed on a distributed computation platform according to the input data space and the workflow configuration.
