We provide a simple proof of the Moreau-Rockafellar theorem that a proper lower semicontinuous convex function on a Banach space is determined up to a constant by its ...

Abstract: Problems of data classification can be studied in the framework of regularization theory as ill-posed problems. In this framework, loss functions play an important role in the application of ...

I want to plot a concave hull of a function, but have noticed that ConvexHull sometimes fails when this function is convex and decreasing. I've appended a minimum breaking example in which ConvexHull ...

This paper proposes a unilateral Adaptive update strategy based Interval Prediction (AIP) model for short-term load prediction, which is developed based on lower and upper bound estimation (LUBE) ...
