+Kernels in GenSVM
+-----------------
+
+Kernels in GenSVM are implemented as follows.
+
+- Radial Basis Function (RBF):
+
+.. math::
+
+  k(x_1, x_2) = \exp(-\gamma \| x_1 - x_2 \|^2 )
+
+- Polynomial:
+
+.. math::
+
+  k(x_1, x_2) = (\gamma x_1'x_2 + coef)^{degree}
+
+- Sigmoid:
+
+.. math::
+
+  k(x_1, x_2) = \tanh(\gamma x_1'x_2 + coef)
