About
Building reliable intelligence for strategic worlds.
Profile / 2026
I am Guo Jiaxing, a researcher and engineer working across computational game theory, machine learning, and reliable decision-making.
My current work asks how an intelligent system should act when information is partial, evidence is unreliable, and other agents can adapt to its behavior.
I build mathematical interfaces, evaluation methods, and research software that make these questions precise enough to test.

Working principles
01
Make the claim inspectable.
A strong result states its assumptions, evidence, and failure conditions.
02
Test the strongest response.
Strategic reliability requires evaluation against adaptive behavior.
03
Build for reproduction.
Research code should make each important choice visible and repeatable.
