TLDR: Twin Learning for Dimensionality Reduction

1 code implementation18 Oct 2021 Yannis Kalantidis, Carlos Lassance, Jon Almazan, Diane Larlus

Dimensionality reduction methods are unsupervised approaches which learn low-dimensional spaces where some properties of the initial space, typically the notion of "neighborhood", are preserved.

Learning with Average Precision: Training Image Retrieval with a Listwise Loss

2 code implementations ICCV 2019 Jerome Revaud, Jon Almazan, Rafael Sampaio de Rezende, Cesar Roberto de Souza

Recent deep models for image retrieval have outperformed traditional methods by leveraging ranking-tailored loss functions, but important theoretical and practical problems remain.

Re-ID done right: towards good practices for person re-identification

no code implementations16 Jan 2018 Jon Almazan, Bojana Gajic, Naila Murray, Diane Larlus

In this paper we adopt a different approach and carefully design each component of a simple deep architecture and, critically, the strategy for training it effectively for person re-identification.

End-to-end Learning of Deep Visual Representations for Image Retrieval

4 code implementations25 Oct 2016 Albert Gordo, Jon Almazan, Jerome Revaud, Diane Larlus

Second, we build on the recent R-MAC descriptor, show that it can be interpreted as a deep and differentiable architecture, and present improvements to enhance it.
