optuna.integration.botorch.qehvi_candidates_func
- optuna.integration.botorch.qehvi_candidates_func(train_x, train_obj, train_con, bounds)[source]
Quasi MC-based batch Expected Hypervolume Improvement (qEHVI).
The default value of
candidates_func
inBoTorchSampler
with multi-objective optimization when the number of objectives is three or less.See also
qei_candidates_func()
for argument and return value descriptions.Note
Added in v2.4.0 as an experimental feature. The interface may change in newer versions without prior notice. See https://github.com/optuna/optuna/releases/tag/v2.4.0.
