Figure 3.

SVM test results and the discriminability index. (A) SVM classification performance as a function of the excitatory coupling strength J_exc and the inhibitory coupling scaling factor j_inh (obeying J_inh = ϵ · J_exc · j_inh). The coupling values representing the non-attended and attended conditions in Figure 2B are marked by a cross and a circle, respectively. (B) Discriminability index in the coupling space for the same spectra. For both (A,B), the strength of the background noise was c_mix = 0.2.
