Leveraging Contrastive Learning for Semantic Segmentation with Consistent Labels Across Varying Appearances

no code implementations21 Dec 2024 Javier Montalvo, Roberto Alcover-Couso, Pablo Carballeira, Álvaro García-Martín, Juan C. SanMiguel, Marcos Escudero-Viñolo

This paper introduces a novel synthetic dataset that captures urban scenes under a variety of weather conditions, providing pixel-perfect, ground-truth-aligned images to facilitate effective feature alignment across domains.

Pinpoint Counterfactuals: Reducing social bias in foundation models via localized counterfactual generation

no code implementations12 Dec 2024 Kirill Sirotkin, Marcos Escudero-Viñolo, Pablo Carballeira, Mayug Maniparambil, Catarina Barata, Noel E. O'Connor

When applied to the Conceptual Captions dataset for creating gender counterfactuals, our method results in higher visual and semantic fidelity than state-of-the-art alternatives, while maintaining the performance of models trained using only real data on non-human-centric tasks.

Improved transferability of self-supervised learning models through batch normalization finetuning

1 code implementation Applied Intelligence 2024 Kirill Sirotkin, Marcos Escudero-Viñolo, Pablo Carballeira, Álvaro García-Martín

At a cost of extra training of only 0. 16% model parameters, in case of ResNet-50, we acquire a proxy task that (i) has a stronger correlation with end-to-end finetuned performance, (ii) improves the linear probing performance in the many- and few-shot learning regimes and (iii) in some cases, outperforms both linear probing and end-to-end finetuning, reaching the state-of-the-art performance on a pathology dataset.

Gradient-based Class Weighting for Unsupervised Domain Adaptation in Dense Prediction Visual Tasks

no code implementations1 Jul 2024 Roberto Alcover-Couso, Marcos Escudero-Viñolo, Juan C. SanMiguel, Jesus Bescós

In unsupervised domain adaptation (UDA), where models are trained on source data (e. g., synthetic) and adapted to target data (e. g., real-world) without target annotations, addressing the challenge of significant class imbalance remains an open issue.

Attention-based Knowledge Distillation in Multi-attention Tasks: The Impact of a DCT-driven Loss

no code implementations4 May 2022 Alejandro López-Cifuentes, Marcos Escudero-Viñolo, Jesús Bescós, Juan C. SanMiguel

Feature-based Knowledge Distillation is a subfield of KD that relies on intermediate network representations, either unaltered or depth-reduced via maximum activation maps, as the source knowledge.

Semantic Driven Multi-Camera Pedestrian Detection

no code implementations27 Dec 2018 Alejandro López-Cifuentes, Marcos Escudero-Viñolo, Jesús Bescós, Pablo Carballeira

Contrarily to the majority of the methods of the state-of-the-art, the proposed approach is scene-agnostic, not requiring a tailored adaptation to the target scenario\textemdash e. g., via fine-tunning.
