WebJan 10, 2024 · Huber loss function compared against Z and Z². The joint can be figured out by equating the derivatives of the two functions. Our focus is to keep the joints as smooth as possible. This becomes the easiest when the two slopes are equal. So let’s differentiate both functions and equalize them. WebSmooth L1 loss is closely related to HuberLoss, being equivalent to huber (x, y) / beta huber(x,y)/beta (note that Smooth L1’s beta hyper-parameter is also known as delta for Huber). This leads to the following differences: As beta -> 0, Smooth L1 loss converges to L1Loss, while HuberLoss converges to a constant 0 loss. church email listsWebSorted by: 4. One of the reasons we like the Huber penalty is that it is the "Moreau-Yosida regularization" of the absolute value function, which means that. ϕ ( y) = inf u u + 1 2 M ( u − y) 2. So, your optimization problem can be written as. minimize x ∑ i inf u i u i + 1 2 M ( u i − a i T x + b) 2. which is equivalent to. church email addresses directory
