A Fast Smoothing Newton Method for Bilevel Hyperparameter Optimization for SVC with Logistic Loss
Yixin Wang, Qingna Li
Support vector classification (SVC) with logistic loss has excellent theoretical properties in classification problems where the label values are not continuous. In this paper, we…
