An enterprise-grade AI retriever designed to streamline AI integration into your applications, ensuring cutting-edge accuracy.
Denser Retriever combines multiple search technologies into a single platform. It utilizes gradient boosting ( xgboost) machine learning technique to combine:
- Keyword-based searches that focus on fetching precisely what the query mentions.
- Vector databases that are great for finding a wide range of potentially relevant answers.
- Machine Learning rerankers that fine-tune the results to ensure the most relevant answers top the list.
Our experiments on MTEB datasets show that the combination of keyword search, vector search and a reranker via an xgboost model (denoted as ES+VS+RR_n) can significantly improve the vector search (VS) baseline.
The initial release of Denser Retriever provides the following features.
- Supporting heterogeneous retrievers such as keyword search, vector search, and ML model reranking
- Leveraging xgboost ML technique to effectively combine heterogeneous retrievers
- State-of-the-art accuracy on MTEB Retrieval benchmarking
- Demonstrating how to use Denser retriever to power an end-to-end applications such as chatbot and semantic search
