1. Activation functions. Write a program Metivat ionfunction. java to compute various actioation functions that arise in mounl nctwerks. An actrintion function is a function that maps real numbers into a desired ratge, such as berween 0 and 1 or between $$?1$$ and $$+1$$. The Hewiside step function is given by $$w(n)=?\begin{array}{ll}0& 4?c\\ 1& a?=0\\ 1& a?=0\\ 1& a?=0\end{array}$$ - The sigmoid function is given by $$\text{ a die }=\frac{1}{1+{}^{1+0}}$$ - The hyperbolic tangent function is given by $$\cos (x)=\frac{x^4?e^{??}}{x^2+e^7}$$ The soffsign function is given by $$A(x)=\frac{a}{1+ix}$$ The square manlinearity function is given by All activation functions should return NaN (not a somber) if the argument is NaN, To do so, organixe your peogram according to the follosine public API: Here are some sample executions: 1. Activation functions. Write a program ActivationFunction, java to compute various activation finctions that arise in neural nctiosrlss An activation function is a function that maps real numbers inte a desired range, sach as between 0 and $$I$$ or between $$?1$$ and $$+1$$. - The Heaviside step function is given by o The sigmaid function is given by $$x(x)=\frac{1}{1+N^{?1}}$$ - The heperbolic saugent function is given by $$\text{ tand }(n)=\frac{c^{+?}}{4+?}$$ - The sofisign function is given by $$f(i)=\frac{t}{1+X}$$ -. The square nonlinearity function is given by All activation functions should retum $$\mathrm{NaN}$$ (net a number) if the aryumsent is NaN. To do so, organize your program acconding to the follewine poblic API: Here are some sample executions:
