WebJun 8, 2024 · erf () is used to compute element wise Gauss error function. Syntax: tensorflow.math.erf ( x, name) Parameters: x: It’s the input tensor. Allowed dtypes are bfloat16, half, float32, float64. name (optional): It defines the name for the operation. Returns: It returns a tensor of same dtype as x. Example 1: Python3 import tensorflow as tf Weberf (X) represents the error function of X . If X is a vector or a matrix, erf (X) computes the error function of each element of X. Examples Error Function for Floating-Point and Symbolic Numbers Depending on its arguments, erf can return floating-point or exact symbolic results. Compute the error function for these numbers. chris cimperman actor

WebJul 1, 2012 · These functions are important because they are encountered in many branches of applied mathematics, in particular probability theory. Namely, if X is a Gaussian random variable with mean 0 and standard deviation 1 / 2, the probability P (− x ⩽ X ⩽ x) is equal to erf (x) (Fig. 1).See [1] for instance for other applications..
