Sizhe Li

Hi! I’m Sizhe, a final-year undergrad at the Chinese University of Hong Kong, Shenzhen, majoring in statistics. I am fortunate to be advised by Prof. Tongxin Li and Prof. Nicolas Christianson. I was also a visiting student at UC, Berkeley during 2024 Fall.

My research focuses on learning-augmented online algorithms and algorithms with predictions. I am particularly interested in decision-making under uncertainty, where the challenge is to design algorithms that leverage predictions while maintaining strong worst-case guarantees.

In a complete theory there is an element corresponding to each element of reality. A sufficient condition for the reality of a physical quantity is the possibility of predicting it with certainty, without disturbing the system. In quantum mechanics in the case of two physical quantities described by non-commuting operators, the knowledge of one precludes the knowledge of the other. Then either (1) the description of reality given by the wave function in quantum mechanics is not complete or (2) these two quantities cannot have simultaneous reality. Consideration of the problem of making predictions concerning a system on the basis of measurements made on another system that had previously interacted with it leads to the result that if (1) is false then (2) is also false. One is thus led to conclude that the description of reality as given by a wave function is not complete.
