The dependence on the number of categories of the performance of E-learning for a classification problem.

<p> (A) The average minimum number of epochs required for correct learning, as a function of the load , for various numbers of categories . Regardless of , the points fall on the same curve. (B) The maximum load for which correct learning is achieved (the capacity ), as a function of the number of categories . The shaded area represents the uncertainty due to the fact that the load can vary only discretely, in steps of , for a particular . The capacity is approximately constant for all .
