SPACE: Semantic Projection and Alignment of CLIP Embeddings for Domain Adaptation
João Renato Ribeiro Manesco, Danilo Samuel Jodas, Douglas Rodrigues +2
A fundamental challenge in deploying vision models is domain shift, which arises when training and test data follow different distributions, leading to degraded performance. This c…
Constraining the orbit of the retrograde planet in the Octantis system
Alan Cefali Signor, Alexandre C. M. Correia, Maria Helena Moreira Morais +4
The Octantis system is composed of a compact stellar binary and a retrograde S-type planet orbiting near the edge of stability. Here, we investigate the dynamically viable arch…
Context-Aware Interpretable Representations for Retrieval and Graph Convolutional Network Classification
Thiago César Castilho Almeida, Gustavo Rosseto Letício, Vinicius Atsushi Sato Kawai +1
The advances in visual information modeling and representation during the last decades are remarkable, mainly supported by Convolutional Neural Networks, Transformer-based, and Fou…
Effective Graph and Rank-based Contextual Embeddings for Textual and Multimedia Data
Thiago César Castilho Almeida, Gustavo Rosseto Letício, Lucas Pascotti Valem +2
In a data-driven world, efficiently organizing and mapping relationships between objects is crucial. Graphs are powerful tools for modeling these connections, being widely used in…
Dynamical formation of long-period exoplanets systems in evolving binary stars
Isabel J. Lima, Rafael R. Sousa, Silvia M. Giuliatti Winter +4
The dynamical formation and evolution of long-period giant exoplanets have not been well constrained due to the few observational parameters. In this study, we explore the dynamica…
Scattering, bound states, and resonances in the one-dimensional Dirac equation via supersymmetric quantum mechanics
Camila C. Soares, Luis B. Castro, Antonio S. de Castro
We develop a unified treatment of scattering and discrete spectra for the one-dimensional Dirac equation with scalar and vector interactions. Under the spin-symmetry condition, the…
