Research Challenges in Designing Differentially Private Text Generation Mechanisms

Accurately learning from user data while ensuring quantifiable privacy guarantees provides an opportunity to build better ML models while maintaining user trust.Recent literature has demonstrated the applicability of a generalized form of Differential Privacy to provide guarantees over text queries.Such mechanisms add privacy preserving noise to vectorial representations of text in high dimension and return a text based projection of Spacecraft Model Kit the noisy vectors.However, these mechanisms are sub-optimal in their trade-off between privacy and utility.In this proposal paper, we describe some challenges in balancing this trade-off.
At a high level, we provide two proposals: (1) a framework called LAC which defers some of the noise to a privacy amplification step and (2), an additional suite of three different techniques for calibrating the noise based on the local region around a word.Our objective in this paper is not to evaluate a single solution Wooden Shape Sorting but to further the conversation on these challenges and chart pathways for building better mechanisms.
