    Kernel Parameters:
    
      - Kernel Type:
        - Polynomial: polynomial kernel
- RBF: radial basis function (gaussian) kernel
- Kernel Width: inverse variance for the kernel function,
        determines the radius of influence of each sample (RBF)
- Degree: degree of the polynomial (Poly)
