Fast and Exact Least Absolute Deviations Line Fitting via Piecewise Affine Lower-Bounding
Stefan Volz, Martin Storath, Andreas Weinmann
Least-absolute-deviations (LAD) line fitting is robust to outliers but computationally more involved than least squares regression. Although the literature includes linear and near…

Degrees-of-freedom penalized piecewise regression
Stefan Volz, Martin Storath, Andreas Weinmann
Many popular piecewise regression models rely on minimizing a cost function on the model fit with a linear penalty on the number of segments. However, this penalty does not take in…
