Sample-Optimal Estimation of the Fréchet Inception Distance

Ziyun Chen, Jerry Li, Kevin Tian وآخرون · 2026

The Fréchet Inception Distance (FID) is widely used to evaluate generative models, but its empirical plug-in estimator suffers from finite-sample bias [BSAG18, CF20]. We study the sample complexity $n$ of estimating FID to error $ε$ between $d$-dimensional Gaussians with bounded mean distance and covariances, when one …

Finding Gaussian Structure in Bosonic States

Alvan Arulandu, Sitan Chen, Ziyun Chen وآخرون · 2026

We study agnostic tomography of pure bosonic Gaussian states: given copies of an arbitrary $n$-mode bosonic state $ρ$, the goal is to output a pure Gaussian state whose infidelity with $ρ$ is at most $\mathrm{opt} + ε$, where $\mathrm{opt}$ is the minimum infidelity achievable by any pure Gaussian state. We give effici …
