WebThe softmax function transforms each element of a collection by computing the exponential of each element divided by the sum of the exponentials of all the elements. That is, if x is a one-dimensional numpy array: softmax(x) = np.exp(x)/sum(np.exp(x)) Parameters: xarray_like. Input array. axisint or tuple of ints, optional. WebApproach: Import math module using the import keyword. Give the list as static input and store it in a variable. Give the first number as static input and store it in another variable. Apply math.tanh () function to the given first number to get the hyperbolic tangent value of a given number. Store it in another variable. Print the above result. gymnastics videos for kids on youtube https://jdmichaelsrecruiting.com
