RobustTrend: A Huber Loss with a Combined First and Second Order Difference Regularization for Time Series Trend Filtering [PDF]

open access: yesarXiv, 2019
Extracting the underlying trend signal is a crucial step to facilitate time series analysis like forecasting and anomaly detection. Besides noise signal, time series can contain not only outliers but also abrupt trend changes in real-world scenarios. To deal with these challenges, we propose a robust trend filtering algorithm based on robust statistics
