Shown here is the performance over all test cases of calcium binding (Table2) as a function of the size of the training corpus. Performance is measured by the area under the ROC graph produced by each example. On the top, each test case is shown as a separate line, each with a different color. Note that while with only a few training examples, the correct pocket is found in most tests, a few harder test cases require more training before they can be reliably predicted. On the bottom is the same data, but averaged, with error bars indicating 95% confidence intervals.
