Towards Federated RLHF with Aggregated Client Preference for LLMs

ICLR 2025poster

Reinforcement learning with human feedback (RLHF) fine-tunes a pretrained large language model (LLM) using user preference data, enabling it to generate content aligned with human preferences. However, due to privacy concerns, users may be reluctant to share sensitive preference data. To address thi…

Towards Universal Debiasing for Language Models-based Tabular Data Generation

EMNLP 2025

Large language models (LLMs) have achieved promising results in tabular data generation. However, inherent historical biases in tabular datasets often cause LLMs to exacerbate fairness issues, particularly when multiple advantaged and protected features are involved. In this work, we introduce a uni

FIARSE: Model-Heterogeneous Federated Learning via Importance-Aware Submodel Extraction

NeurIPS 2024poster

In federated learning (FL), accommodating clients' varied computational capacities poses a challenge, often limiting the participation of those with constrained resources in global model training. To address this issue, the concept of model heterogeneity through submodel extraction has emerged, off…
