Convert a rate parameter from optimizer space to physical space. This transformation maps unconstrained real values to the interval (0, 1) using the logistic sigmoid function.

Parameters:

x (float | numpy.ndarray) – Rate parameter in optimizer space.

Returns:

Rate parameter in physical space.

Return type:

float | numpy.ndarray
