Without reading the linked paper: Huber's loss was introduced by Huber in 1964 in the context of estimating a one-dimensional location of a distribution. In this context, the mean (average) is the estimator optimising L2-loss, and the median is the estimator optimising L1-loss. The mean is very vulnerable to extreme outliers.

Web17 Jun 2024 · Decreasing learning rate doesn't have to help. the plot above is not the loss plot. I would recommend some type of explicit average smoothing, e.g. use a lambda layer that computes the average of the last 5 values on given axis then use this layer after your LSTM output and before your loss. – Addy.
