WebMay 20, 2024 · The Huber Loss offers the best of both worlds by balancing the MSE and MAE together. We can define it using the following piecewise function: What this equation essentially says is: for loss values less than delta, use the MSE; for loss values greater than delta, use the MAE. WebMar 11, 2024 · To tackle the problem of heavy-tailed errors, huber-type robust technique provides potential solutions. The classical Huber loss (Huber 1964) is a hybrid of squared loss for relatively small errors and absolute loss for relatively large errors, where the degree of hybridization is controlled by one tuning parameter.
