A network that uses the outer product rule, hidden neurons, and peaks in the energy landscape
Geoffrey W. Hoffmann, M.R. Davenport · 2002
The results of the development and simulation of an extended version of the discrete Hopfield neural network are summarized. The network uses hidden neurons to optimize the orthogonality of the memory space. The process is fast because it is noniterative, and the design is such that a hardware implementation would require no executive processor during memory storage or retrieval. Simulations indicate that the storage capacity of the network and the radius of attraction of each memory are significantly better for uncorrelated memories than those of the standard Hopfield model. Hidden neurons permit flexibility in the network capacity for memories of a given length and make it possible for the network to solve second-order problems.>
