Robust Sparse Identification of Nonlinear Dynamics via Least Trimmed Squares
ILTS-SINDy decouples outlier filtering via iterative least trimmed squares from sparse regression via sequentially thresholded least squares, showing better performance than prior robust SINDy variants on data with up to 20% corruption.
