Generalized Graph Variational Autoencoders: Bounded Divergences Control Posterior Collapse
Kleyton da Costa, Bernardo Modenesi, Ivan F. M. Menezes +1
The variational graph autoencoder (VGAE) regularizes its posterior toward the prior with the Kullback-Leibler divergence, a choice inherited from the variational autoencoder rather…
Robust topology optimization with non-Gaussian material fields using polygonal finite elements
Nilton Cuellar, Anderson Pereira, Ivan F. M. Menezes +1
We present a computational framework for robust topology optimization that integrates polygonal finite-element discretizations, spatially correlated non-Gaussian material modeling,…
Divergence-Guided Particle Swarm Optimization
Kleyton da Costa, Bernardo Modenesi, Ivan F. M. Menezes +1
Particle Swarm Optimization (PSO) is susceptible to premature convergence when the swarm collapses around the global best, particularly on multimodal landscapes in higher dimension…
Non-intrusive polynomial chaos expansion for topology optimization using polygonal meshes
Nilton Cuellar, Anderson Pereira, Ivan F. M. Menezes +1
This paper deals with the applications of stochastic spectral methods for structural topology optimization in the presence of uncertainties. A non-intrusive polynomial chaos expans…
Accelerating engineering design by automatic selection of simulation cases through Pool-Based Active Learning
J. H. Gaspar Elsas, N. A. G. Casaprima, I. F. M. Menezes
A common workflow for many engineering design problems requires the evaluation of the design system to be investigated under a range of conditions. These conditions usually involve…
Topology Optimization Using Polytopes
Arun L. Gain, Glaucio H. Paulino, Leonardo Duarte +1
Meshing complex engineering domains is a challenging task. Arbitrary polyhedral meshes can provide the much needed flexibility in automated discretization of such domains. The geom…
