Spectral Souping: A Unified Framework for Online Preference Alignment
Researchers have developed "Spectral Souping," a novel framework designed to align large language models with individual user preferences more effectively than traditional RLHF methods. This approach identifies a universal spectral representation within LLMs that facilitates model merging. The framework first trains specialized policies offline for different preference dimensions, then uses an online adaptation algorithm to combine these policies at inference time, allowing for rapid adaptation without costly retraining.
