Applying AI to Automate Credit Decisions at Facebook

Managing credit limits for Facebook’s advertisers requires thousands of credit decisions annually. We built a machine learning solution to help automate credit decisions. It uses gradient boosted decision trees to predict whether an account’s invoices will become bad debt with 92.4% ROC-AUC. This enabled Facebook to reduce manual credit decision volume by 62% while avoiding revenue loss resulting from accounts reaching their credit limits.
