Meta-Mathematics of Algebraic Complexity
Michal Garlik, Svyatoslav Gryaznov, Jiaqi Lu +2
We initiate the study of the meta-mathematics of algebraic circuit lower bounds, aiming both to gain insight into the methods sufficient and necessary to prove algebraic circuit lo…

Sharp Characterization of Bias in Post-Bandit Inference
Lisu Wang, Yilun Chen, Jiaqi Lu
Bandit algorithms generate data for downstream inference, but adaptive sampling biases post-bandit sample means. We analyze this bias for stable index algorithms, including UCB1 an…

Bandit Allocational Instability
Yilun Chen, Jiaqi Lu
When multi-armed bandit (MAB) algorithms allocate pulls among competing arms, the resulting allocation can exhibit huge variation. This is particularly harmful in modern applicatio…
