Capacity at finite .

<p>a,b. as a function of for the SP model and Parameters are chosen to optimize capacity under the binomial approximation. Shown are the result of the gaussian approximation without covariance (cyan) and with covariance (magenta) for these parameters. c. Optimized as a function of for the SP model at . The blue curve is for patterns with fluctuations in the number of selective neurons. The red curve is for the same number of selective neurons in all patterns. The black curve is the number of patterns that would be stored if the network were storing the same amount of information as in the case . d. Same for the MP model, where parameters have been optimized, but the depression-potentiation ratio is fixed at .
