Enabling Differentially Private Federated Learning for Speech Recognition: Benchmarks, Adaptive Optimizers, and Gradient Clipping

#114 · Martin Pelikan, Sheikh Shams Azam, Vitaly Feldman, Jan Silovsky, Kunal Talwar, Christopher Brinton, Tatiana Likhomanenko

We introduce the first practical benchmark for FL with DP in ASR, combining theoretical insights on gradient heterogeneity with empirical results that demonstrate scalability and strong performance under user-level privacy guarantees.

PREAMBLE: Private and Efficient Aggregation via Block Sparse Vectors

#5516 · Hilal Asi, Vitaly Feldman, Hannah Keller, Guy N. Rothblum, Kunal Talwar

We show that private vector aggregation can be done with sublinear communication in the two-server setting, with efficient protocols and zero-knowledge proofs.
