Reuse out-of-year data to enhance land cover mappingvia feature disentanglement and contrastive learning

no code implementations17 Apr 2024 Cassio F. Dantas, Raffaele Gaetano, Claudia Paris, Dino Ienco

Typically, when creating a land cover (LC) map, precise ground truth data is collected through time-consuming and expensive field campaigns.

Masking Strategies for Background Bias Removal in Computer Vision Models

1 code implementation23 Aug 2023 Ananthu Aniraj, Cassio F. Dantas, Dino Ienco, Diego Marcos

Models for fine-grained image classification tasks, where the difference between some classes can be extremely subtle and the number of samples per class tends to be low, are particularly prone to picking up background-related biases and demand robust methods to handle potential examples with out-of-distribution (OOD) backgrounds.

Towards Explainable Land Cover Mapping: a Counterfactual-based Strategy

no code implementations4 Jan 2023 Cassio F. Dantas, Diego Marcos, Dino Ienco

Furthermore, plausibility/realism of the generated counterfactual explanations is enforced via the proposed adversarial learning strategy.

Expanding boundaries of Gap Safe screening

1 code implementation22 Feb 2021 Cassio F. Dantas, Emmanuel Soubies, Cédric Févotte

In this work, we extend the existing Gap Safe screening framework by relaxing the global strong-concavity assumption on the dual cost function.
