Digital Signal Analysis based on Convolutional Neural Networks for Active Target Time Projection Chambers
G. F. Fortino, J. C. Zamora, L. E. Tamayose +2
An algorithm for digital signal analysis using convolutional neural networks (CNN) was developed in this work. The main objective of this algorithm is to make the analysis of exper…
On the discovery of stars, quasars, and galaxies in the Southern Hemisphere with S-PLUS DR2
L. Nakazono, C. Mendes de Oliveira, N. S. T. Hirata +25
This paper provides a catalogue of stars, quasars, and galaxies for the Southern Photometric Local Universe Survey Data Release 2 (S-PLUS DR2) in the Stripe 82 region. We show that…
Self-supervised Learning for Astronomical Image Classification
Ana Martinazzo, Mateus Espadoto, Nina S. T. Hirata
In Astronomy, a huge amount of image data is generated daily by photometric surveys, which scan the sky to collect data from stars, galaxies and other celestial objects. In this pa…
Greenery Segmentation In Urban Images By Deep Learning
Artur A. M. Oliveira, Nina S. T. Hirata, Roberto Hirata
Vegetation is a relevant feature in the urban scenery and its awareness can be measured in an image by the Green View Index (GVI). Previous approaches to estimate the GVI were base…
Deep Learning Multidimensional Projections
Mateus Espadoto, Nina S. T. Hirata, Alexandru C. Telea
Dimensionality reduction methods, also known as projections, are frequently used for exploring multidimensional data in machine learning, data science, and information visualizatio…
Symbol detection in online handwritten graphics using Faster R-CNN
Frank D. Julca-Aguilar, Nina S. T. Hirata
Symbol detection techniques in online handwritten graphics (e.g. diagrams and mathematical expressions) consist of methods specifically designed for a single graphic type. In this…
