svm multi-classification 2

Although some parameters have reached 94%, some parameters are only 80%

Consider whether there is a problem with the range of cg 2 * (-10) to (10)

And you can also try to refine the parameters, the step size is 0.5

 

1. Check which parameters have reached the boundary, and expand the cg parameter range

2. If you want to improve the acc, do more refinement and step down
