Figure 1From: Nonnegative principal component analysis for mass spectral serum profiles and biomarker discoveryComparison on the five algorithm performance. Comparison on the five algorithm performance on four datasets: 'O1' (ovarian), 'O2' (ovarian-qaqc), 'L' (liver), and 'C' (colorectal). The NPCA-SVM algorithm demonstrated leading performance over the other four algorithms.Back to article page
