Enhancing Model Privacy in Federated Learning with Random Masking and Quantization

EMNLP 2025

The primary goal of traditional federated learning is to protect data privacy by enabling distributed edge devices to collaboratively train a shared global model while keeping raw data decentralized at local clients. The rise of large language models (LLMs) has introduced new challenges in distribut

Advancing Parameter Efficiency in Fine-tuning via Representation Editing

ACL 2024long

Parameter Efficient Fine-Tuning (PEFT) has gained significant attention for its ability to achieve competitive results while updating only a small subset of trainable parameters. Despite the promising performance of current PEFT methods, they present challenges in hyperparameter selection, such as d…

Aligning Large Language Models with Human Preferences through Representation Engineering

ACL 2024long

Aligning large language models (LLMs) with human preferences is crucial for enhancing their utility in terms of helpfulness, truthfulness, safety, harmlessness, and interestingness. Existing methods for achieving this alignment often involve employing reinforcement learning from human feedback (RLHF…

Promoting Data and Model Privacy in Federated Learning through Quantized LoRA

EMNLP 2024finding

Conventional federated learning primarily aims to secure the privacy of data distributed across multiple edge devices, with the global model dispatched to edge devices for parameter updates during the learning process. However, the development of large language models (LLMs) requires substantial dat…
