ezmsg.sigproc.activation#

Functions

activation(function)[source]#

Transform the data with a simple activation function.

Parameters:: function (str | ActivationFunction) – An enum value from ActivationFunction or a string representing the activation function. Possible values are: SIGMOID, EXPIT, LOGIT, LOGEXPIT, “sigmoid”, “expit”, “logit”, “log_expit”. SIGMOID and EXPIT are equivalent. See scipy.special.expit for more details.
Return type:: ActivationTransformer

Returns: ActivationTransformer
