ATM Fraud Detection Using Outlier Detection

2018
A fraud detection model that applies accounts’ behavior features and outlier detection methods are proposed. Given a set of transactions, the accounts are grouped into two groups according to the location that the transactions took place, i.e., ‘local-only’ and ‘has-abroad’.
