WebHuber loss. In Section III, we produce a strictly convex, smooth and robust loss from the generalized formulation. In Section IV, we design an algorithmwhichminimizes such loss … Web14 apr. 2024 · This paper proposes a generalization of the local bootstrap for periodogram statistics when weakly stationary time series are contaminated by additive outliers. To achieve robustness, we suggest replacing the classical version of the periodogram with the M-periodogram in the local bootstrap procedure. The robust bootstrap periodogram is … ser student search

Webhqreg-package Regularization Paths for Lasso or Elastic-net Penalized Huber Loss Regression and Quantile Regression Description Efficient algorithms for fitting regularization paths for lasso or elastic-net penalized regression mod-els with Huber loss, quantile loss or squared loss. Details Package: hqreg Type: Package Version: 1.4 Date: … WebThe Huber loss is both differen-tiable everywhere and robust to outliers. A disadvantage of the Huber loss is that the parameter α needs to be selected. In this work, we propose an intu-itive and probabilistic interpretation of the Huber loss and its parameter α, which we believe can ease the process of hyper-parameter selection.
