Regularized Least Squares Training of Quadratic Neural Networks with Applications to System Identification
Read the original on arXiv Machine Learning →The paper introduces a least‑squares method for training quadratic neural networks with regularization, providing a lower bound on the training optimization problem when the regularization coefficient is positive. It delivers closed‑form expressions for both the approximate solution and its sensitivity to data errors, and shows that the solution is optimal when the regularization coefficient is zero. The approach offers computational advantages over iterative methods like backpropagation and is validated on a nonlinear system identification example.
