Web22 Mar 2024 · Smooth L1 loss, also known as Huber loss, is mathematically given as: $$loss (x,y)=\begin {cases} 0.5 (x-y)^2, if x-y <1\\ x-y -0.5, otherwise \end {cases}$$ The squared term loss is used when the absolute loss falls below 1 and uses an absolute term otherwise. This makes it less sensitive to outliers and prevents exploding gradients.
