    • The kernel function can be any of the following:
      • linear [math]\displaystyle{ \langle x, x'\rangle }[/math].
      • polynomial [math]\displaystyle{ (\gamma \langle x, x'\rangle + r)^d }[/math]. d is specified by keyword degree, r by coef0.
      • rbf [math]\displaystyle{ \exp(-\gamma |x-x'|^2). \gamma }[/math] is specified by keyword gamma, must be greater than 0.
      • sigmoid [math]\displaystyle{ (\tanh(\gamma \langle x,x'\rangle + r)) }[/math], where r is specified by coef0.
