The radial basis kernel with default gamma creates 367 support vectors, out of which, 184 belong to level 𝙲𝙷 and remaining 183 belong to level 𝙼𝙼. The classifier has a training error of 14.7% and a test error of 15.6% which is a slight improvement over linear kernel. We now use cross validation to find optimal gamma.
