optuna.integration.botorch.qnehvi_candidates_func
- optuna.integration.botorch.qnehvi_candidates_func(train_x, train_obj, train_con, bounds)[source]
Quasi MC-based batch Expected Noisy Hypervolume Improvement (qNEHVI).
According to Botorch/Ax documentation, this function may perform better than qEHVI (qehvi_candidates_func). (cf. https://botorch.org/tutorials/constrained_multi_objective_bo )
