Searching for Optimal Solutions with LLMs via Bayesian Optimization

ICLR 2025poster

Scaling test-time compute to search for optimal solutions is an important step towards building generally-capable language models that can reason. Recent work, however, shows that tasks of varying complexity require distinct search strategies to solve optimally, thus making it challenging to design…

Hybrid Hierarchical Retrieval for Open-Domain Question Answering

ACL 2023findings

Retrieval accuracy is crucial to the performance of open-domain question answering (ODQA) systems. Recent work has demonstrated that dense hierarchical retrieval (DHR), which retrieves document candidates first and then relevant passages from the refined document set, can significantly outperform th…
