Inference-Free Multimodal Learned Sparse Retrieval for Production-Scale Visual Document Search

Gyu-Hwung Cho, Youngjune Lee, Kiyoon Jeong +5

As large-scale visual-document corpora such as arXiv papers and enterprise PDFs continue to grow, visual-document retrieval has gained increasing attention; yet it still lacks a de…

Efficient Listwise Reranking with Compressed Document Representations

Hervé Déjean, Stéphane Clinchant

Reranking, the process of refining the output from a first-stage retriever, is often considered computationally expensive, especially when using Large Language Models (LLMs). A com…

On the Challenges and Opportunities of Learned Sparse Retrieval for Code

Simon Lupart, Maxime Louis, Thibault Formal +2

Retrieval over large codebases is a key component of modern LLM-based software engineering systems. Existing approaches predominantly rely on dense embedding models, while learned…

Learning Retrieval Models with Sparse Autoencoders

Thibault Formal, Maxime Louis, Hervé Dejean +1

Sparse autoencoders (SAEs) provide a powerful mechanism for decomposing the dense representations produced by Large Language Models (LLMs) into interpretable latent features. We po…
