Gap-free Differentially Private PCA for Gaussian Data

The paper presents a gap‑free differentially private algorithm for performing principal component analysis on Gaussian data. It addresses the PCA problem while ensuring privacy guarantees without relying on a spectral gap assumption. The work is announced on arXiv with the identifier 2609.31614v1.

Differentially Private Neural Network Training Under the Hidden State Assumption

arXiv:2407. 08233v3 Announce Type: replace Abstract: Current differentially private learning paradigms face a severe utility bottleneck: DP-SGD degrades performance through noise accumulation over training steps, while aggregation-based approaches such as PATE suffer from data inefficiency due to disjoint data partitioning.
