Figure 7

Receiver operating characteristic (ROC) curves of serum SERS spectra for classifying bladder cancer patients and normal subjects with PCA-LDA and GA-LDA algorithms together with the leave-one spectrum-out cross-validation technique.

The integration area under the ROC curves for PCA-LDA and GA-LDA are 0.920 and 0.986, respectively, illustrating the efficient performance of GA-LDA in bladder cancer diagnosis with serum SERS.
