cupyx.scipy.special.log_expit#

cupyx.scipy.special.log_expit = <ufunc 'cupy_log_expit'>#

Logarithm of the logistic sigmoid function.

Parameters

x (cupy.ndarray) – input data (must be real)

Returns

values of log(expit(x))

Return type

cupy.ndarray

Note

The function is mathematically equivalent to log(expit(x)), but is formulated to avoid loss of precision for inputs with large (positive or negative) magnitude.
