Can Compressing Retrieved Documents Boost Language Model Performance? This AI Paper Introduces RECOMP: Improving Retrieval-Augmented LMs with Compression and Selective Augmentation

Optimizing their efficiency whereas managing computational sources is a vital problem in an more and more highly effective language mannequin period. Researchers from The College of Texas at Austin and the College of Washington explored an modern technique that compresses retrieved paperwork into concise textual summaries. By using each extractive and abstractive compressors, their method efficiently enhances the effectivity of language fashions. 

Effectivity enhancements in Retrieval-Augmented Language Fashions (RALMs) are a focus, specializing in enhancing the retrieval parts by strategies like knowledge retailer compression and dimensionality discount. Methods to cut back retrieval frequency embody selective retrieval and the utilization of bigger strides. Their paper “RECOMP” contributes a novel method by compressing retrieved paperwork into succinct textual summaries. Their method not solely reduces computational prices but additionally enhances language mannequin efficiency. 

Addressing the restrictions of RALMs, their research introduces RECOMP (Retrieve, Compress, Prepend), a novel method to boost their effectivity. RECOMP includes compressing retrieved paperwork into textual summaries earlier than in-context augmentation. Their course of makes use of each an extractive compressor to pick pertinent sentences from the paperwork and an abstractive compressor to synthesize info right into a concise abstract. 

Their technique introduces two specialised compressors, an extractive and an abstractive compressor, designed to boost language fashions’ (LMs) efficiency on finish duties by creating concise summaries from retrieved paperwork. The extractive compressor selects pertinent sentences, whereas the abstractive compressor synthesizes knowledge from a number of paperwork. Each compressors are skilled to optimize LM efficiency when their generated summaries are added to the LM’s enter. Analysis contains language modeling and open-domain question-answering duties, and transferability is demonstrated throughout numerous LMs.

Their method is evaluated on language modeling and open-domain question-answering duties, attaining a outstanding 6% compression price with minimal efficiency loss, surpassing commonplace summarization fashions. The extractive compressor excels in language fashions, whereas the abstractive compressor performs greatest with the bottom perplexity. In open-domain query answering, all retrieval augmentation strategies improve efficiency. Extractive oracle leads and DPR performs nicely amongst extractive baselines. The skilled compressors switch throughout language fashions in language modeling duties. 

RECOMP is launched to compress retrieved paperwork into textual summaries, enhancing LM efficiency. Two compressors, extractive and abstractive, are employed. The compressors are efficient in language modeling and open-domain question-answering duties. In conclusion, compressing retrieved paperwork into textual summaries improves LM efficiency whereas lowering computational prices.

Future analysis instructions, together with adaptive augmentation with the extractive summarizer, enhancing compressor efficiency throughout totally different language fashions and duties, exploring various compression charges, contemplating neural network-based fashions for compression, experimenting on a broader vary of features and datasets, assessing generalizability to different domains and languages, and integrating different retrieval strategies like doc embeddings or question enlargement to boost retrieval-augmented language fashions.
