DiffPO: Diffusion-styled Preference Optimization for Inference Time Alignment of Large Language Models

ACL 2025long

Inference-time alignment provides an efficient alternative for aligning LLMs with humans. However, these approaches still face challenges, such as limited scalability due to policy-specific value functions and latency during the inference phase. In this paper, we propose a novel approach, Diffusion-…

Breaking the Communication-Privacy-Accuracy Tradeoff with $f$-Differential Privacy

NeurIPS 2023poster

We consider a federated data analytics problem in which a server coordinates the collaborative data analysis of multiple users with privacy concerns and limited communication capability. The commonly adopted compression schemes introduce information loss into local data while improving communication…

Spectral Co-Distillation for Personalized Federated Learning

NeurIPS 2023poster

Personalized federated learning (PFL) has been widely investigated to address the challenge of data heterogeneity, especially when a single generic model is inadequate in satisfying the diverse performance requirements of local clients simultaneously. Existing PFL methods are inherently based on the…
