Optimizing log transportation in the Argentinean forest industry by column generation
(Elsevier Science, 2021-04)
A column generation based algorithm for optimally solving a daily log routing problem in the Argentinean forest industry is presented in this work. Minimum-cost truck-routes are dynamically generated by two complementary ...
An investigation of the activation process of high temperature shift catalyst
(ELSEVIER SCIENCE BV, 2008)
The aim of this work is to address the activation process of a high temperature shift (HTS) catalyst, composed of Fe2O3/Cr2O3/CuO, by analyzing it before activation (HTS-V) and after activation (HTS-A) using complementary ...
Maximum entropy-based reinforcement learning using a confidence measure in speech recognition for telephone speech
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2010)
In this paper, a novel confidence-based reinforcement learning (RL) scheme to correct observation log-likelihoods and to address the problem of unsupervised compensation with limited estimation data is proposed. A two-step ...
