A computationally efficient nonlinear least squares method using random basis functions
Date of Original Version
A method to obtain parameter estimates in a nonlinear least squares problem is proposed. Its main advantage is computational efficiency and can be used when a direct grid search cannot. The approach is based on the theory of random basis functions. An example of its application to frequency estimation is given and other applications discussed. © 1994-2012 IEEE.
