Topology offers a way to organize complex data by looking for shape, structure, and relationships. Yusu Wang, Ph.D., UC San Diego, and Gunnar E. Carlsson, Ph.D., Stanford University, discuss how ideas from algebraic topology move from pure mathematics into data science, machine learning, and AI. Carlsson explains why topological data analysis helps identify meaningful groups in large data sets, how examples and accessible tools can make abstract math useful, and why interpretability matters as AI systems grow more complex. The conversation connects collaboration across fields, customer-focused entrepreneurship, and the need to train mathematicians and AI researchers to help formulate real-world problems. Their exchange shows how mathematical thinking can make powerful technologies more understandable, usable, and accountable. [8/2026] [Show ID: 41487]

FAQ
Q: What is topological data analysis?
A: Topological data analysis applies topology, the mathematical study of shape, to data. Carlsson describes it as a way to organize complex data, identify meaningful groups, and understand how those groups are similar or different.
Q: How can topology help AI?
A: Topological methods can help examine large-scale patterns inside neural networks, including relationships between features in different layers. Carlsson says this kind of structure matters because AI systems need understanding and guidance, not just more compute and data.
Q: What does Carlsson say researchers should learn from startups?
A: A useful tool does not succeed just because the math is strong. Researchers need to understand potential users, study what people are willing to do, and think through the business case before building a startup.](https://i.ytimg.com/vi/JYZVs7LUdEM/hqdefault.jpg)
