Actually, All Learnable Distribution Classes Are Privately Learnable

arXiv cs.LG ↗ · 2026-10-22 Cached

该论文证明了所有在总变差距离下可学习的分布类也都是可私有学习的,从而证实了Ashtiani的一个猜想,即在(ε,δ)-差分隐私约束下,只要目标误差可以任意小,有限样本下的可学习性依然成立。

Generalized TV--$\ell_p$ Structured Priors for Bayesian $T_1$ Mapping

arXiv cs.LG ↗ · 2026-06-05 Cached

This paper proposes an extended family of structured spatial priors combining total variation (TV) with ℓ_p norms for Bayesian T1 mapping, enabling uncertainty quantification. The method is evaluated on synthetic and real MRI datasets, showing improved spatial coherence and reduced uncertainty.
