متن کاملThe Double-Barrelled LASSO
We present a new method which solves a double-barelled LASSO in a convex least squares approach. In the presented method we focus on the scenario where one is interested in (or limited to) a primal (feature) representation for the first view while having a dual (kernel) representation for the second view. DB-LASSO minimises the number of features used in both the primal and dual projections whi...
متن کاملAmbiguity without a State Space
Many decisions involve both imprecise probabilities and intractable states of the world. Objective expected utility assumes unambiguous probabilities; subjective expected utility assumes a completely specified state space. This paper analyzes a third domain of preference: sets of consequential lotteries. Using this domain, we develop a theory of Knightian ambiguity without explicitly invoking a...

متن کاملRings of Integers without a Power Basis
Let K be a number field, with degree n and ring of integers OK . When OK = Z[α] for some α ∈ OK , the set {1, α, . . . , αn−1} is a Z-basis of OK . We call such a basis a power basis. When K is a quadratic field or a cyclotomic field, OK admits a power basis, and the use of these two fields as examples in algebraic number theory can lead to the impression that rings of integers should always ha...
