On the equivalence between algorithms for non-negative matrix factorization and latent Dirichlet allocation
(European Neural Network Society - ENNSBruges, 2016-04)
LDA (Latent Dirichlet Allocation ) and NMF (Non-negative Matrix Factorization) are two popular techniques to extract topics in a textual document corpus. This paper shows that NMF with Kullback-Leibler divergence approximate ...

A mathematical model for determining timetables that minimizes the number of students with conflicting schedules
(2013-10-25)
With the increasing complexity of educational initiatives, several challenges arise as to appropriately allocate human and material resources or how to select alternative investments within a portfolio. Due to the complexity, ...
A Proposal for Reliability Evaluation of Components on Electric Power Distribution System Integrating Probabilistic Models and Fuzzy Inference Systems
(Ieee, 2012-01-01)
The system reliability depends on the reliability of its components itself. Therefore, it is necessary a methodology capable of inferring the state of functionality of these components to establish reliable indices of ...
Mathematical Modeling of Industrial Optimization Problems
(2016)
We address three optimization problems arising from the industry: Mine Planning Production Scheduling; Crew Scheduling for Train Transportation; and Optimal Resource Allocation in Public Education Systems.
A Multiobjective Model for Distribution System Planning based on Tabu Search
