An outlier-resistance phase retrieval algorithm based on alternating direction method of multipliers (ADMM) is devised in this letter. Instead of the widely used least squares criterion that is only optimal for Gaussian noise environment, we adopt the least absolute deviation criterion to enhance the robustness against outliers. Considering both intensityand amplitude-based observation models, ...

The impact of the Parkinson's disease and its treatment on the patients' health-related quality of life can be estimated either by means of generic measures such as the european quality of Life-5 Dimensions (EQ-5D) or speci ̄c measures such as the 8-item Parkinson's disease questionnaire (PDQ-8). In clinical studies, PDQ-8 could be used in detriment of EQ-5D due to the lack of resources, time or...

Appendix A: Nonlinear regression model and nonlinear approximation methods In this section, we extend the approximation approaches that we developed in Sections 4.2 and 4.3 to the case of the nonlinear regression model y = Ψ (kk a; b) + εε (A.1) where b ∈ R n+1 , k ≡ (k 0 k T −1) ∈ R T , a ≡ (a 0 a T −1) ∈ R T , and Ψ (kk a; β) ≡ (Ψ (k 0 a 0 ; β) Ψ (k T −1 a T −1 ; β)) ∈ R T. 1 We first conside...

Moral absolutes have little or no moral standing in our morally diverse modern society. Moral relativism is far more palatable for most ethicists and to the public at large. Yet, when pressed, every moral relativist will finally admit that there are some things which ought never be done. It is the rarest of moral relativists that will take rape, murder, theft, child sacrifice as morally neutral...
