Forward and Backward Uncertainty Quantification in Optimization
This contribution gathers some of the ingredients presented during the Iranian Operational Research community gathering in Babolsar in 2019.It is a collection of several previous publications on how to set up an uncertainty quantification (UQ) cascade with ingredients of growing computational complexity for both forward and reverse uncertainty propagation.
متن کاملMoving Forward Moving Backward: Directional Sorting of Chemotactic Cells due to Size and Adhesion Differences
Differential movement of individual cells within tissues is an important yet poorly understood process in biological development. Here we present a computational study of cell sorting caused by a combination of cell adhesion and chemotaxis, where we assume that all cells respond equally to the chemotactic signal. To capture in our model mesoscopic properties of biological cells, such as their s...
متن کاملGeneralized Forward-Backward Splitting
This paper introduces the generalized forward-backward splitting algorithm for minimizing convex functions of the form F + ∑i=1Gi, where F has a Lipschitzcontinuous gradient and the Gi’s are simple in the sense that their Moreau proximity operators are easy to compute. While the forward-backward algorithm cannot deal with more than n = 1 non-smooth function, our method generalizes it to the cas...
متن کاملForward-Backward Reinforcement Learning
Goals for reinforcement learning problems are typically defined through handspecified rewards. To design such problems, developers of learning algorithms must inherently be aware of what the task goals are, yet we often require agents to discover them on their own without any supervision beyond these sparse rewards. While much of the power of reinforcement learning derives from the concept that...
متن کاملForward-backward Semiclassical Dynamics
Computing the time evolution of quantum systems composed of many coupled degrees of freedom presents serious challenges. Currently, simulations of timedependent properties in polyatomic molecules, clusters, or condensed phases employ a variety of approximations, which are largely built around variational, quantum-classical or semiclassical ideas. While approximate methods have proven extremely ...
