InRanker: Distilled Rankers for Zero-shot Information Retrieval

no code implementations12 Jan 2024 Thiago Laitz, Konstantinos Papakostas, Roberto Lotufo, Rodrigo Nogueira

Despite multi-billion parameter neural rankers being common components of state-of-the-art information retrieval pipelines, they are rarely used in production due to the enormous amount of compute required for inference.

ExaRanker: Explanation-Augmented Neural Ranker

1 code implementation25 Jan 2023 Fernando Ferraretto, Thiago Laitz, Roberto Lotufo, Rodrigo Nogueira

Recent work has shown that inducing a large language model (LLM) to generate explanations prior to outputting an answer is an effective strategy to improve performance on a wide range of reasoning tasks.

NeuralSearchX: Serving a Multi-billion-parameter Reranker for Multilingual Metasearch at a Low Cost

no code implementations26 Oct 2022 Thales Sales Almeida, Thiago Laitz, João Seródio, Luiz Henrique Bonifacio, Roberto Lotufo, Rodrigo Nogueira

We compare our system with Microsoft's Biomedical Search and show that our design choices led to a much cost-effective system with competitive QPS while having close to state-of-the-art results on a wide range of public benchmarks.
