Truncated loss
WebSep 10, 2014 · The loss function \(\mathrm{robust}({{\mathbf w}},b,{{\mathbf x}})\) in the optimization model is a sum of two truncated Hinge loss functions, which is a bilateral truncated Hinge loss function. We know the truncated Hinge loss function is neither differentiable nor convex so that most convex optimization methods cannot be employed … WebNov 1, 2005 · Truncated Stop Loss as Optimal Reinsurance Agreement in One-period Models. We consider several one-period reinsurance models and derive a rule which minimizes the ruin probability of the cedent for a fixed reinsurance risk premium. The premium is calculated according to the economic principle, generalized zero-utility …

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.
