Figure 1.

The performance analysis on simulated datasets. The solid lines indicate the average values; and dotted lines indicate one standard deviation from the averages. The X-axis represents the number of genes in Si. Note that, when the generating process goes, the number of genes in Si decreases. (a) The classification accuracy θtest on the test samples. (b) The classification accuracy θtrain on the training samples. (c) The percentage psim (i) of truly discriminative genes in Si; (d) The p-value ρS(i) based on <a onClick="popup('http://www.biomedcentral.com/1471-2164/9/S2/S18/mathml/M2','MathML',630,470);return false;" target="_blank" href="http://www.biomedcentral.com/1471-2164/9/S2/S18/mathml/M2">View MathML</a>(Ai).
