ARTEMIS: Attention-based Retrieval with Text-Explicit Matching and Implicit Similarity

1 code implementation ICLR 2022 Ginger Delmas, Rafael Sampaio de Rezende, Gabriela Csurka, Diane Larlus

While the first provides rich and implicit context for the search, the latter explicitly calls for new traits, or specifies how some elements of the example image should be changed to retrieve the desired target image.

Probabilistic Embeddings for Cross-Modal Retrieval

4 code implementations CVPR 2021 Sanghyuk Chun, Seong Joon Oh, Rafael Sampaio de Rezende, Yannis Kalantidis, Diane Larlus

Instead, we propose to use Probabilistic Cross-Modal Embedding (PCME), where samples from the different modalities are represented as probabilistic distributions in the common embedding space.

StacMR: Scene-Text Aware Cross-Modal Retrieval

1 code implementation8 Dec 2020 Andrés Mafla, Rafael Sampaio de Rezende, Lluís Gómez, Diane Larlus, Dimosthenis Karatzas

Then, armed with this dataset, we describe several approaches which leverage scene text, including a better scene-text aware cross-modal retrieval method which uses specialized representations for text from the captions and text from the visual scene, and reconcile them in a common embedding space.

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.
