Fig. 2

Average character recognition rate with changing number of repetitions for the IC and C paradigms. ‘C’ and ‘IC’ are the abbreviations for congruent and incongruent, respectively. The average character recognition rate obtained by SWLDA is shown on the left of a, and the average character recognition rate obtained by SVM is on the right of a. In addition, the results of the incongruent and congruent paradigm are colored dark blue and dark red, respectively. b Shows the significant p values of the two classification methods for the IC and C paradigms. The blue dotted curve represents the SWLDA results and the red dotted curve illustrates the SVM results. The yellow solid curve is the significance level of p value 0.05
