Figure 6. Importance of the kernels in the final solution in a FSMKL approach.

This figure shows the importance of each kernel in the final solution. Non-zero values indicate the informative kernels. For each group of textural features we used several different types of kernels, the final decision function were only considering polynomial (with 1 and 2 degrees of freedom) and Gaussian kernels (with low values for the free parameter).
