optuna_integration.botorch.qnei_candidates_func(train_x, train_obj, train_con, bounds, pending_x)

Quasi MC-based batch Noisy Expected Improvement (qNEI).

This function may perform better than qEI (qei_candidates_func) when the evaluated values of objective function are noisy.

See also

qei_candidates_func() for argument and return value descriptions.

Note

Added in v3.3.0 as an experimental feature. The interface may change in newer versions without prior notice. See https://github.com/optuna/optuna/releases/tag/v3.3.0.

• train_x (torch.Tensor) –

• train_obj (torch.Tensor) –

• train_con (torch.Tensor | None) –

• bounds (torch.Tensor) –

• pending_x (torch.Tensor | None) –

Return type:

torch.Tensor
