Coincidence Detection Using Spiking Neurons with Application to Face Recognition

Figure 11

Convergence analysis on (a) Supervised STDP and (b) Prediction using different spike codings (c) shows the comparison on spike error of Supervised STDP and the Prediction learning methods as the training iteration grows. The errors are taken as average of recognition error from AR Scream S1 and Scarf S1. The recognition error at in (a) and (b) is not shown for clarity of the graph. For Supervised STDP, recognition error for RO coding is not shown since for all tested epochs.
