title: Community-Cross-Instruct: Unsupervised Instruction Generation for Aligning Large Language Models to Online Communities
abstract: Social scientists use surveys to probe the opinions and beliefs of populations, but these methods are slow, costly, and prone to biases.Recent advances in large language models (LLMs) enable the creation of computational representations or "digital twins" of populations that generate human-like responses mimicking the population's language, styles, and attitudes.We introduce COMMUNITY-CROSS-INSTRUCT, an unsupervised framework for aligning LLMs to online communities to elicit their beliefs.Given
