Multistability of neural networks with discontinuous non-monotonic piecewise linear activation functions and time-varying delays
Discontinuous non-monotonic piecewise linear activation functions are introduced. Multiple equilibriums of neural networks with time-varying delays are investigated. n n -dimensional discontinuous neural networks with delays can have 5n 5 n equilibriums. 3n 3 n equilibriums are locally stable and the others 5n?3n 5 n ? 3 n are unstable. Discontinuous NNs can have greater storage capacity than continuous NNs.
