Truncated huber penalty function
Web% For matrices and N-D arrays, the penalty function is applied to each % element of X independently. M and T must be compatible with X in the same % sense as .*: one must be a scalar, or they must have identical size. % % Disciplined convex programming information: % HUBER is jointly convex in X and T. It is nonomonotonic in X and WebSinogram restoration with the Huber penalty is able to provide better resolution-noise performance than restoration with a quadratic penalty. ...

When … WebJan 25, 2024 · The loss function (5) is known as truncated Huber loss (see Fig. 1 (a)). In fact, it gives loss fixed at 1 for t > 1 + δ / 2, which yields robustness to outliers, while pays loss fixed at 0 for t < 0, which receives sparsity. Obviously, truncated Huber loss is sparser or more robust to outliers than hinge loss, huberized pinball loss and Huber ...
