Augmented Dense Sparse Retrieval Github This project aims to produce an enhanced retriever for longer korean sequences, jointly taking advantages of sparse and dense passage embeddings by noah lee, ji hun keom. In this work, we propose a solution in the form of mixture of retrievers (mor) framework.
Scaling Sparse And Dense Retrieval In Decoder Only Llms Our framework transforms an arbitrary dense llm into a parameter efficient sparse mixture of experts (moe) model capable of handling complex reasoning tasks, including both single and multi hop queries. We walk through the steps of integrating sparse and dense vectors for knowledge retrieval using amazon opensearch service and run some experiments on some public datasets to show its advantages. the full code is available in the github repo aws samples opensearch dense spase retrieval. Building on these insights, we propose a simple neural model that combines the efficiency of dual encoders with some of the expressiveness of more costly attentional architectures, and explore sparse dense hybrids to capitalize on the precision of sparse retrieval. Pyserini makes it easy to do sparse retrieval (bm25, rm3, etc.) and also integrates some dense retrieval (it provides pre built indexes and models for dpr, etc., and can do hybrid.
Github Oriram Dense Retrieval Projections Building on these insights, we propose a simple neural model that combines the efficiency of dual encoders with some of the expressiveness of more costly attentional architectures, and explore sparse dense hybrids to capitalize on the precision of sparse retrieval. Pyserini makes it easy to do sparse retrieval (bm25, rm3, etc.) and also integrates some dense retrieval (it provides pre built indexes and models for dpr, etc., and can do hybrid. In this paper, we analyze the original dense passage retrieval method using the bert backbone. we analyze dpr from multiple perspectives to understand what is changing in the backbone model during the training process. As a result, choosing the right retrieval algorithm has become a critical area of research. this study evaluates and compares sparse and dense retrieval algorithms, aiming to identify how rag system performance can be optimized under varying resource constraints and user requirements.

Retrieval augmented generation (rag) is powerful, but its effectiveness hinges on which retrievers we use and how. different retrievers offer distinct, often complementary signals: bm25 captures lexical matches; dense retrievers, semantic similarity.
