Figure 4. The overall accuracy of the input features using different groups of mutation types.

Four groups of mutation types, “missense mutation group” (red bar), “synonymous nonsynonymous mutation group” (green bar), “high impact mutation group” (blue bar) and “total mutation group” (orange bar), were selected as input features for cancer type classification. Each of the four groups of mutation types were used as input features predicted by the eight classifiers. The height of each bar represents the average number, and the error bar is the standard deviation.
