Hierarchical surrogate modeling for illumination algorithms [PDF]
Proceedings of the Genetic and Evolutionary Computation Conference Companion, 2017 Evolutionary illumination is a recent technique that allows producing many diverse, optimal solutions in a map of manually defined features. To support the large amount of objective function evaluations, surrogate model assistance was recently introduced.

Evaluation of Surrogate Animal Models of Melioidosis [PDF]
Frontiers in Microbiology, 2010 Burkholderia pseudomallei is the Gram-negative bacterial pathogen responsible for the disease melioidosis. B. pseudomallei establishes disease in susceptible individuals through multiple routes of infection, all of which may proceed to a septicemic disease associated with a high mortality rate. B.

Scalable Transformer for PDE Surrogate Modeling
Advances in Neural Information Processing Systems 36, 2023 Transformer has shown state-of-the-art performance on various applications and has recently emerged as a promising tool for surrogate modeling of partial differential equations (PDEs). Despite the introduction of linear-complexity attention, applying Transformer to problems with a large number of grid points can be numerically unstable and ...

Linear and nonlinear time series analysis of the black hole candidate Cygnus X-1
, 1999 We analyze the variability in the X-ray lightcurves of the black hole candidate Cygnus X-1 by linear and nonlinear time series analysis methods. While a linear model describes the over-all second order properties of the observed data well, surrogate data
