a$)$ The weight matrix is symmetric.

b$)$ A unit can be connected to itself.

c$)$ The units in a Hopfield network can be updated randomly during recall.

Which of the following statements is true for the centers of the Gaussian activation functions of radial basis function networks?

b$)$ They are the values of the activation functions.

c$)$ They define the width of the activation functions.

d$)$ They are the prototype vectors.

What is the minimum number of units $(N)$ necessary to store and recall six patterns successfully by a Hopfield neural network? The theoretical limit for the maximum number of patterns that can be stored is given by $\frac{N}{2lnN},$ where $N$ is the number of network units.
