The S-PLUS: a star/galaxy classification based on a Machine Learning approach
M. V. Costa-Duarte, L. Sampedro, A. Molino +32
We present a star/galaxy classification for the Southern Photometric Local Universe Survey (S-PLUS), based on a Machine Learning approach: the Random Forest algorithm. We train the…
MAXIMUM LIKELIHOOD AND MINIMUM ENTROPY IDENTIFICATION OF GRAMMARS
P. Collet, A. Galves, A. Lopes
Using the Thermodynamic Formalism, we introduce a Gibbsian model for the identification of regular grammars based only on positive evidence. This model mimics the natural language…
Estimating stellar population and emission line properties in S-PLUS galaxies
J. Thainá-Batista, R. Cid Fernandes, F. R. Herpich +10
We present tests of a new method to simultaneously estimate stellar population and emission line (EL) properties of galaxies out of S-PLUS photometry. The technique uses the AlStar…
C*-Algebras, Approximately Proper Equivalence Relations, and Thermodynamic Formalism
R. Exel, A. Lopes
We introduce a non-commutative generalization of the notion of (approximately proper) equivalence relation and propose the construction of a "quotient space". We then consider cert…
