Compound decision theory
WebNov 26, 2024 · In a compound decision problem, consisting of n statistically independent copies of the same problem to be solved under the sum of the individual losses, any reasonable compound decision rule δ satisfies a natural symmetry property, entailing that δ(σ(y)) = σ(δ(y)) for any permutation σ.

WebWhat help are theories to ethical decision-making in a business? • The principles identified by theories help managers by providing a systematic rationale to make ethical decisions in business ie to decide what is ‘right’ or ‘wrong’ • Such decisions may be reached by applying one such theory or possibly a plurality of theories • An individual making an ethical … Web3.3. Decision-Making Rule. In DS evidence theory, two common decision-making rules are maximum belief function and maximum plausibility function method. But it is obvious that both of them are too simple to obtain accurate and satisfactory recognition results in IR/MMW system. Therefore, a compound decision-making rule is applied.
WebIn this paper, we study a new approach to estimating high-dimensional covariance matrices. We first frame covariance matrix estimation as a compound decision problem. This motivates defining a class of decision rules and using a nonparametric empirical Bayes g-modeling approach to estimate the optimal rule in the class.
