DataReal.get_activation_outhead

DataReal.get_activation_outhead() → str | torch.nn.Module | None[source]

Tries to interfere the activation function for the output head, based on the last transformation. It follows the following rules:

  • If the last transformation is a MinMaxScaler with a target range of (0, 1), the activation function is sigmoid.

  • If the last transformation is a MinMaxScaler with a target range of (-1, 1), the activation function is tanh.

  • Otherwise, no activation function is inferred. None is returned.

Returns:

Optional[Union[str, nn.Module]] – Activation function for the output head.
