Oracle Inequalities for Convex Loss Functions with Non-Linear Targets
Mehmet Caner, Anders Bredahl Kock
This paper consider penalized empirical loss minimization of convex loss functions with unknown non-linear target functions. Using the elastic net penalty we establish a finite sam…
Fibrations as Eilenberg-Moore algebras
Anders Kock
We give an elementary exposition of some fundamental facts about fibered (or rather opfibered) categories, in terms of monads and 2-categories. The account avoids any mention of ca…
Projective lines as groupoids with projection structure
Anders Kock
The coordinate projective line over a field is seen as a groupoid with a further `projection' structure. We investigate conversely to what extent such an, abstractly given, groupoi…
Oracle Inequalities for High-Dimensional Panel Data Models
Anders Bredahl Kock
This paper is concerned with high-dimensional panel data models where the number of regressors can be much larger than the sample size. Under the assumption that the true parameter…
