Betting on Bets: Anytime-Valid Tests for Stochastic Dominance

Sebastian Arnold, Yo Joong Choe, Marco Scarsini +1

How can we monitor, in real time, whether one uncertain prospect has any upside over another? To answer this question, we develop a novel family of sequential, anytime-valid tests…

Combining Evidence Across Filtrations

Yo Joong Choe, Aaditya Ramdas

In sequential anytime-valid inference, any admissible procedure must be based on e-processes: generalizations of test martingales that quantify the accumulated evidence against a c…

The Geometry of Categorical and Hierarchical Concepts in Large Language Models

Kiho Park, Yo Joong Choe, Yibo Jiang +1

The linear representation hypothesis is the informal idea that semantic concepts are encoded as linear directions in the representation spaces of large language models (LLMs). Prev…
