Composite Code Sparse Autoencoders for first stage retrieval

Carlos Lassance, Thibault Formal, Stephane Clinchant

We propose a Composite Code Sparse Autoencoder (CCSA) approach for Approximate Nearest Neighbor (ANN) search of document representations based on Siamese-BERT models. In Informatio…

A White Box Analysis of ColBERT

Thibault Formal, Benjamin Piwowarski, Stéphane Clinchant

Transformer-based models are nowadays state-of-the-art in ad-hoc Information Retrieval, but their behavior is far from being understood. Recent work has claimed that BERT does not…
