Building Payment Classification Models from Rules and Crowdsourced Labels: A Case Study. |
Abstract | ||
|---|---|---|
The ability to classify customer-to-business payments enables retail financial institutions to better understand their customers’ expenditure patterns and to customize their offerings accordingly. However, payment classification is a difficult problem because of the large and evolving set of businesses and the fact that each business may offer multiple types of products, e.g. a business may sell both food and electronics. Two major approaches to payment classification are rule-based classification and machine learning-based classification on transactions labeled by the customers themselves (a form of crowdsourcing). The rules-based approach is not scalable as it requires rules to be maintained for every business and type of transaction. The crowdsourcing approach leads to inconsistencies and is difficult to bootstrap since it requires a large number of customers to manually label their transactions for an extended period of time. This paper presents a case study at a financial institution in which a hybrid approach is employed. A set of rules is used to bootstrap a financial planner that allowed customers to view their transactions classified with respect to 66 categories, and to add labels to unclassified transactions or to re-label transactions. The crowdsourced labels, together with the initial rule set, are then used to train a machine learning model. We evaluated our model on real anonymised dataset, provided by the financial institution which consists of wire transfers and card payments. In particular, for the wire transfer dataset, the hybrid approach increased the coverage of the rule-based system from 76.4% to 87.4% while replicating the crowdsourced labels with a mean AUC of 0.92, despite inconsistencies between crowdsourced labels. |
