Cancer type classification accuracy of the Infinium 850 K array testing datasets. A Sample number and prediction accuracy (%) of 15 cancer types. B Confusion matrix (in percent) of the cancer type prediction using 200 selected probes for testing datasets generated by infinium 850 K methylation array. The percentages of correctly predicted samples are highlighted in green; misclassification events are highlighted in pink. True histology/predicted histology is respectively listed in rows/columns.
