Noise-Aware Shrinkage for Differentially Private Zeroth-Order Fine-Tuning of Large Language Models

arXiv:2608. 03277v1 Announce Type: new Abstract: Differentially private zeroth-order optimization (DP-ZO) enables memory-efficient private fine-tuning of large language models using only forward evaluations.

Component-Aware Differential Privacy for Federated Multilingual Speech-LLMs

The paper introduces a per-layer differential privacy (DP) clipping strategy for federated multilingual speech large language models (speech‑LLMs). It demonstrates that standard single‑pool per‑layer DP methods fail due to a cross‑component budget collapse caused by large norm differences between acoustic encoders and language decoders. The authors propose an α‑split two‑pool allocation that normalises encoder and decoder parameters separately, preserving the overall DP guarantee while restoring word error rate performance and providing tighter noise protection for the encoder.

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.

RAPTOR: Role-Aware Private Training for Mixture-of-Experts

arXiv:2609.05770v1 Announce Type: new Abstract: Differentially private (DP) fine-tuning methods treat sparse Mixture-of-Experts (MoE) models as a single dense block, ignoring that shared layers see a...
