### How can we prove that an autoassociator network will continue to perform if we zero the diagonal elements of a weight matrix?

How can I we prove that an autoassociator network will continue to perform if we zero the diagonal elements of a weight matrix that has been determined by the Hebb rule. In other words, suppose that the weight matrix is determined from: $W = PP^T- QI$ where $Q$ is the number of prototype vectors. Hint…
