Adoption of Big Data and Machine Learning in CORE Business Processes
by VP, Global Commercial & Merchant Data Science, American Express
Given the huge volumes of data available (both structured and un-structured) for American Express Card Members, American Express has adopted Machine Learning in all its CORE business processes of Credit and Fraud Risk Management, Marketing Analytics and Operation. Work entailed building in-house data warehouses with right level of privacy controls and then using state of art machine learning algorithms from Open Sources to solve unique business problems across the various businesses. Adoption of Machine Learning has ensured building of Robust Economic Models leveraging the best possible information delivering the highest predictive power. Also the models are updated with the highest frequency ensuring the models incorporate the most fresh information. This has led to significant improvement in the controls for Fraud Risk and also improved the Targeting of the Appropriate segments with far higher accuracy in Marketing.
As a part of the presentation, I will take through 3-4 actual use cases of CORE American Express processes and how Machine Learning is completely changed the game.
Discussion will also include what are the new areas where the company is thinking of doing research and bringing the best value for its Card Members.
