Scatterplot of classification rates of CASUT with (a) CSP, (b) CCSP, (c) SUTCCSP, and (d) the overlapping results of (a), (b), and (c). Note that most of the dots are located above the dotted green line, which indicates higher performance of CASUT.

(a) CSP (%)

(b) CCSP (%)

(c) SUTCCSP (%)

(d) All CSP methods (%)
