Sarah Langford of Integrity Management Services, Inc. (IntegrityM) will present an overview of bias in fraud detection and prevention systems, providing insight on the points at which bias can be introduced and how to identify and prevent it. This informative and interactive presentation will take place during the Financial Intelligence & Information Sharing Working Group (FIIS WG) 2017 Summer Symposium on Wednesday, June 21, 2016 in New York City.
Effective detection and prevention of bias in fraud detection is essential to achieving accurate and reliable results. Ms. Langford will detail four types of bias, explain at what point in the cycle bias occurs, best practices to avoid and address bias, and the effect on results when there is failure to recognize bias.
For example, chronological bias can be introduced when comparing historical data to current data or using current data to predict future patterns. When models fail to account for events and trends that will cause significant differences between timeframes, the outcome of results can raise alerts for potential fraud — and in some cases, fail to detect potential fraud.
Ms. Langford will demonstrate how utilizing best practices will increase the overall effectiveness of results when running complex statistical analysis for fraud detection and prevention. High-level concepts will be broken down into a relatable, intuitive approach.
