A strength of echo state networks is the simple method used to train the output layer - typically a collection of linear readout weights found using a least squares approach.

In this paper, we study a simple iterative method for finding the Dantzig selector, which was designed for linear regression problems.

In this paper, we propose using the Dantzig selector model incorporating an overcomplete dictionary to separate a noisy undersampled collection of composite signals, and present an algorithm to efficiently solve the model.
