Anti-adversarial Learning: Desensitizing Prompts for Large Language Model

AAAI 2026technical

With the widespread use of LLMs, preserving privacy in user prompts has become crucial, as prompts risk exposing private and sensitive data to cloud LLMs. Conventional techniques like homomorphic encryption (HE), secure multi-party computation, and federated learning (FL) are not well-suited to this

Transplant Then Regenerate: A New Paradigm for Text Data Augmentation

EMNLP 2025

Data augmentation is a critical technique in deep learning. Traditional methods like Back-translation typically focus on lexical-level rephrasing, which primarily produces variations with the same semantics. While large language models (LLMs) have enhanced text augmentation by their “knowledge emerg
