An EnKF-based scheme to optimize hyper-parameters and features for SVM classifier

作者:

Highlights:

• We adopt the EnKF based scheme to optimize hyper-parameters and features.

• We build the EnKF based framework for parameter optimization.

• Multiple ensemble and ensemble evolution are proposed to enhance effects.

• Householder method is proposed to optimize the EnKF analysis computation.

• The EnKF scheme outperforms three current Bayesian optimization methods.
