Global Tech Summit 2022 | Are those fries really missing
Delivery Hero Felipe Alfaro is a data scientist in Glovo’s fintech data risk team. He started working at Glovo in May 2021 and worked on several projects related to fraud, including the prevention of refund abuse, automatic chargeback disputes and fraud in cash orders. In his talk “Are those fries really missing” he explains the model his team developed to prevent refund abuse.
Takeaways:
- A risk score helps to determine how likely a customer is to be abusive.
- We chose an unsupervised anomaly detection model to identify the most likely abusers.
- Identifying fraudsters among new customers is difficult. We use our customer network spots when a customer is actually new or a fraudster creating a new account to circumvent a ban.
