Researchers from Meta have introduced Retrieval-Augmented Dual Instruction Tuning (RA-DIT), a lightweight fine-tuning methodology to equip large language models (LLMs) with efficient retrieval capabilities. RA-DIT operates through two stages, optimizing the LLM’s use of retrieved information and refining the retriever’s results. It outperforms existing models in knowledge-intensive zero and few-shot learning tasks, showcasing its effectiveness in enhancing LLMs with retrieval capabilities. RA-DIT achieves state-of-the-art results and improves performance in tasks requiring knowledge utilization and contextual awareness.
Meta AI Researchers Introduce RA-DIT: A New AI Approach for Enhanced Language Models
Researchers from Meta have introduced a method called Retrieval-Augmented Dual Instruction Tuning (RA-DIT) to address the limitations of large language models (LLMs) in capturing less common knowledge and the high computational costs of pre-training. RA-DIT is a lightweight fine-tuning method that equips LLMs with retrieval capabilities.
The two-stage fine-tuning process of RA-DIT improves the utilization of retrieved information by LLMs and refines retrievers to provide more relevant results for LLMs. This method outperforms existing retrieval-augmented models in zero and few-shot learning benchmarks, showcasing its effectiveness in enhancing LLMs with retrieval capabilities.
