Silva, Jorge; Derpich, Milan (MDPI AG, 2018)This work demonstrates a formal connection between density estimation with a data-rate constraint and the joint objective of fixed-rate universal lossy source coding and model identification introduced by Raginsky in ...

Espinosa, Sebastian; Silva, Jorge; Mendez, Rene; Lobos, Rodrigo; Orchard Concha, Marcos (EDP Sciences, 2018)Context. Astrometry relies on the precise measurement of positions and motions of celestial objects. Driven by the ever-increasing accuracy of astrometric measurements, it is important to critically assess the maximum ...

Méndez Bussard, René Alejandro; Claveria, Ruben M.; Orchard Concha, Marcos; Silva, Jorge F. (IOP Publishing Ltd., 2017)We present orbital elements and mass sums for 18 visual binary stars of spectral types B to K (five of which are new orbits) with periods ranging from 20 to more than 500 yr. For two double-line spectroscopic binaries with ...

Santibáñez Leal, Felipe; Ortiz, Julián; Silva, Jorge F. (Springer, 2020)Grade control and short-term planning determine the performance of a mining project. Improving this decision, by collecting the most informative samples (data) may have significant financial impact on the project. In this ...

Santibañez, Felipe; Silva, Jorge F.; Ortiz, Julián M. (Springer Verlag, 2019)© 2019, International Association for Mathematical Geosciences.The task of optimal sampling for the statistical simulation of a discrete random field is addressed from the perspective of minimizing the posterior uncertainty ...

Silva, Jorge F.; Piantanida, Pablo (Institute of Electrical and Electronics Engineers, 2020)Motivated from the fact that universal source coding on countably infinite alphabets (infinity-alphabets) is not feasible, this work introduces the notion of "almost lossless source coding". Analog to the weak variable-length ...
