“The product we have is called Decision Intelligence, and that's where in the milliseconds we have between when a transaction passes through our network from when you tap to buy something in a store, it passes through MasterCard to go to the issuer. We're providing a score on that based on how likely that is a good or bad transaction. We use Gen AI, recurring neural networks and other technologies to effectively add features to that. By understanding not just your transaction history, but the overall ecosystem of merchant behaviors and create basically a merchant vector database in there to help understand whether or not this is likely to be a good or bad transaction, even if you've never shopped at that merchant before, because we can see like behaviors from other consumers.”

Ulrich: Centralizing all enterprise AI functions into one department is foolish
“Artificial intelligence, like electricity, like it, it's just a part of so much of the organization. It would be foolish, dangerous, and probably impossible to try to strip out all those elements and centralize them into one place.”
Ulrich: Generative AI solutions are not yet ready for direct consumer use
“There's enthusiasm, but I, it's definitely not unbridled as people are very worried about the accuracy, the hallucination, the efficacy of these, and particularly as you start pointing these to customer facing solutions, there's a very high bar on what that's …”
Ulrich: Traditional ML beats GenAI for structured data and fraud management
“If you have structured data, you're doing forecasting models, a lot of the fraud management, traditional artificial intelligence, machine learning, Is going to be more efficient, more effective, and certainly more cost effective as a way to do it.”
Ulrich: AI reasoning models increasingly decline to answer when uncertain
“It's not just the accuracy that is improving, but the percentage of time, the significant increase in percentage of time that those models will basically say, I don't know the answer to a question.”
Ulrich: Proprietary data and inference will differentiate future AI applications
“I do think that the use of data becomes a more critical differentiator. Inference becomes a more critical differentiator.”
