Approaching Human-Level Forecasting with Language Models

预测未来事件对政策和决策制定非常重要。在这项工作中,我们研究了语言模型(LMs)是否能够在竞争性人类预测者的水平上进行预测。为了实现这个目标,我们开发了一个检索增强的LM系统,旨在自动搜索相关信息,生成预测并聚合预测。为了促进我们的研究,我们收集了来自竞争性预测平台的大量问题数据集。在我们的LMs的知识切断后发布的测试集下,我们评估了我们的系统的端到端性能与人类预测的聚合值相比。平均而言,该系统接近竞争预测者的聚合值,并在某些情况下超过它。我们的工作表明,使用LMs来预测未来可能会提供准确的预测,并帮助机构决策制定。
Forecasting future events is important for policy and decision making. In this work, we study whether language models (LMs) can forecast at the level of competitive human forecasters. Towards this goal, we develop a retrieval-augmented LM system designed to automatically search for relevant information, generate forecasts, and aggregate predictions. To facilitate our study, we collect a large dataset of questions from competitive forecasting platforms. Under a test set published after the knowledge cut-offs of our LMs, we evaluate the end-to-end performance of our system against the aggregates of human forecasts. On average, the system nears the crowd aggregate of competitive forecasters, and in some settings surpasses it. Our work suggests that using LMs to forecast the future could provide accurate predictions at scale and help to inform institutional decision making.
