What do mathematical statisticians do for AI?▼
Develop theory behind ML algorithms. Understand why methods work. Develop new statistical approaches for AI problems. Think deeply about foundations.
Why does theory matter if methods work empirically?▼
Understanding theory enables: better algorithms, knowing when methods fail, developing methods for new problems, proving guarantees and correctness.
What's Bayesian statistics?▼
Framework for updating beliefs (probabilities) with data. Contrast to frequentist. Useful for many ML problems.
What's causal inference?▼
Inferring cause-effect relationships from data. Harder than prediction. Critical for understanding why AI decisions made.
Where do they work?▼
Research labs (Google, Meta, OpenAI, DeepMind), academia, specialized statistical consulting firms.
