Bayesian Optimization using Deep Gaussian Processes

Hebbal, Ali, Brevault, Loic, Balesdent, Mathieu et al.

Understand

Bayesian Optimization using Gaussian Processes is a popular approach to deal with the optimization of expensive black-box functions.

  • However, because of the a priori on the stationarity of the covariance matrix of classic Gaussian Processes, this method may not be adapted for non-stationary functions involved in the optimization problem.
  • To overcome this issue, a new Bayesian Optimization approach is proposed.
  • It is based on Deep Gaussian Processes as surrogate models instead of classic Gaussian Processes.
