NexusAI™ · Fraud detection

Fraud signals on AI-ready financial data

GJEF NexusAI™ prepares ingested ledgers and transaction feeds to full AI-readiness, then runs explainable outlier detection so teams can approve, reject, or escalate findings with a clear audit trail.

How it works

From fragmented files to governed fraud decisions

Detection only runs after the same prepare step used across NexusAI™: standardise, dedupe, and impute so readiness is lifted before modelling. Fraud is one classification path of the production AI Detection Pipeline.

Audit events

Numeric outliers above the median on financial columns are prioritised as fraud candidates; below-median patterns may surface as leakage. Each finding carries category, monetary exposure, record reference, confidence, and an AI explanation.

Illustrative risk engine

A transparent, rule-weighted simulator for education — not a live model score. Production detection uses prepared datasets and statistical outlier analysis inside NexusAI™.
