This loss function involves a measurement of asymmetry r, which the unequal weights of the observed information can depend upon. WebThe method works on simple estimators as well as on nested objects (such as pipelines). The former have parameters of the form __ so that it’s possible to update each component of a nested object.

And it’s more robust to outliers than MSE. Therefore, it combines good properties from both MSE and MAE.
