Fenchel young losses
WebBased upon Fenchel-Young losses [11, 12], we introduce projection-based losses in a broad setting. We give numerous examples of useful convex polytopes and their associated projections. We study the consistency w.r.t. a target loss of interest when combined with calibrated decoding, WebIn subsequent work, this has been coupled with improvement on loss functions in specific applications [44,45]. Our work provides contribution to both these approaches. ... - Our method yields natural connections to the recently-proposed Fenchel-Young losses by Blondel et al. [9]. We show that the equivalence via duality with regularized ...

WebIn this paper, we introduce Fenchel-Young losses, a generic way to construct a convex loss function for a regularized prediction function. We provide an in-depth study of their properties in a very broad setting, covering all the aforementioned supervised learning tasks, and revealing new connections between sparsity, generalized entropies, and ... WebTowards this goal, this paper studies and extends Fenchel-Young losses, recently proposed for structured prediction . We show that Fenchel-Young losses provide a generic and principled way to construct a loss function with an associated predictive probability distribution. We further show that there is a tight and fundamental relation between ...

WebFeb 14, 2024 · On Classification-Calibration of Gamma-Phi Losses. Gamma-Phi losses constitute a family of multiclass classification loss functions that generalize the logistic and other common losses, and have found application in the boosting literature. We establish the first general sufficient condition for the classification-calibration of such losses.
