WebMathematical Formulation − According to Hebbian learning rule, following is the formula to increase the weight of connection at every time step. Δ w j i ( t) = α x i ( t). y j ( t) Here, Δ w j i ( t) ⁡= increment by which the weight of connection increases at time step t. α = the positive and constant learning rate. WebANN structure contains several neurons in which the interconnect calculations are processed. The weights associated with neurons would have a role to strengthen these interconnections. ANN could be created by various multilayer feed forward networks. So far, a three-layer ANN has been developed.
