Figure 2. Relationship between learning speed and neuronal redundancy ().

(A): Learning speed when , or . The bar graph and error bars depict sample means and standard deviations, both of which are calculated using the results of randomly sampled sets of 1000 values. (B): Learning curves when , or . These curves and error bars show averaged values and standard deviations of errors. (C): Relationship between learning speed and the number of model neurons when , or . The horizontal axis represents the number of neurons and the vertical axis represents , where is the learning speed when the number of neurons is . Dotted and solid lines denote the average learning speed and power functions fitted to the values, respectively.
