Simulation and optimization techniques for short-term mine production scheduling
(Universidad de Chile, 2020)
Short-term mine production schedules aim to meet goals previously defined by the long-term mine production schedule. Unfortunately, the complexity and uncertainty of a mine operation cause deviations from the short-term ...
Evaluating loss minimization in multi-label classification via stochastic simulation using beta distribution
(Universidade Federal do Espírito SantoBRPrograma de Pós-Graduação em InformáticaUFESMestrado em Informática, 2016-05-20)
The objective of this work is to present the effectiveness and efficiency of algorithms for solving the loss minimization problem in Multi-Label Classification (MLC). We first prove that a specific case of loss minimization ...
Operative mine planning, design and geological modeling: Integration based on topological representations
(Universidad de Chile, 2017)
Scientific and engineering efforts in mine planning theory are focused on improving the speed and size capacity of existing algorithms. They look for changing from minutes to seconds, and hundreds of thousands to million ...

Plurigaussian simulation of non-stationary categorical variables and its application to ore body modeling
(Universidad de Chile, 2016)
The conditional simulation of geological domains, coded through categorical regionalized variables, allows constructing outcomes (realizations) of the layout of these domains that reproduce their spatial continuity and ...
