Figure 4. Spectrograms of the weighted support vectors on each side of the hyperplane.

Figure 4

The color bars are in dB. (A) The apple spectrograms used as support vectors added up according to their weights. (B) Same as A for corn. Examining the two weighted spectrograms, the idea of the support vectors, being the most difficult data points to separate in the limits of the data set, becomes clearer.
