New method trains quadratic neural networks with closed-form solutions

Researchers have developed a novel least squares approach for training quadratic neural networks, incorporating regularization to establish a lower bound on the optimization problem's solution. This method provides closed-form expressions for the network weights and their sensitivity to data errors, significantly reducing computation time compared to iterative methods like backpropagation. The approach offers analytical expressions for weights and sensitivity, and connects optimization to nuclear norm minimization, demonstrating its utility in a nonlinear system identification example.
