Exceptions as Chance for Computational Chance Discovery

2008
In this paper, we analyze clinical data to model relationships between clinical data and health levels. During analyses of data, we discovered models which are important for determining health levels but cannot be extracted during machine learning process. We regard such models as chance and propose an interactive determination of such models.

Chance-constrained H∞ control for a class of time-varying systems with stochastic nonlinearities: The finite-horizon case

at - Automatisierungstechnik, 2019
In this paper, a new finite-horizon H∞ control problem is considered for a class of time-varying systems with stochastic nonlinearities, measurements degradation and chance constraints.

Chance-Constrained AC Optimal Power Flow: Reformulations and Efficient Algorithms

IEEE Transactions on Power Systems, 2017
Higher levels of renewable electricity generation increase uncertainty in power system operation. To ensure secure system operation, new tools that account for this uncertainty are required.

Data-driven decision making in power systems with probabilistic guarantees: Theory and applications of chance-constrained optimization

Annual Reviews in Control, 2019
Uncertainties from deepening penetration of renewable energy resources have posed critical challenges to the secure and reliable operations of future electric grids.

A chance to learn, a chance to sell

Dental Nursing, 2008
The dental industry is becoming increasingly aware of the enhanced status and importance of dental nurses in decision making in the practice, and is now targeting this hitherto ignored, yet very influential, workforce. Here, we explain the benefit of communicating with company representatives and how to turn that ‘free lunch’ into a reciprocal ...

Topography of chance

Physical Review E, 2013
We present a model of multiplicative Langevin dynamics that is based on two foundations: the Langevin equation and the notion of multiplicative evolution. The model is a nonlinear mechanism transforming a white-noise input to a dynamic-equilibrium output, using a single control: an underlying convex U-shaped potential function. The output is quantified

Chance and Games of Chance

1998
Abstract If your little daughter returns from school saying that two children in her class both had birthdays today and asks, ‘Isn’t that amazing’? then the mathematically correct answer to her question is, ‘No, that is not amazing, it is to be expected every once in a while.’ Although this is not the way you might advise a parent to ...

Emergent Chance

The Nature of Contingency, 2020
This chapter offers a theory of objective chance in the Everettian context, often seen as the main challenge facing EQM. By supplementing diverging EQM with quantum modal realist bridge principles connecting the physics of quantum mechanics with the ...

Data-Driven Chance Constrained Programs over Wasserstein Balls

, 2018
We provide an exact deterministic reformulation for data-driven chance constrained programs over Wasserstein balls. For individual chance constraints as well as joint chance constraints with right-hand side uncertainty, our reformulation amounts to a ...
