Generalization error () and performance when adapting to multiple targets.

<p><b>A.</b> The generalization error <i>vs.</i> the location of the test targets, estimated from simulations as in <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1003377#pcbi-1003377-g006" target="_blank">Figure 6</a>. Shaded area represents one around the averages. Tuning width: . <b>B.</b> The noiseless performance (see Eq(25)), averaged over all the tested targets () is plotted <i>vs.</i> the number of trained targets. See <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1003377#s4" target="_blank">Materials and Methods</a> for details about how this quantity was estimated. Blue: .
