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.
WebGenerally, L2 loss converge faster than l1. But it prone to over-smooth for image processing, hence l1 and its variants used for img2img more than l2. WebOverview; LogicalDevice; LogicalDeviceConfiguration; PhysicalDevice; experimental_connect_to_cluster; experimental_connect_to_host; …

It combines the best properties of L2 squared loss and L1 absolute loss by being strongly convex when close to the target/minimum and less steep for extreme values. The scale at which the Pseudo-Huber loss function transitions from L2 loss for values close to the minimum to L1 loss for extreme values and the steepness at extreme values can be controlled by the value.
