American Economic Review, 2019 We study stochastic choice as the outcome of deliberate randomization. We derive a general representation of a stochastic choice function where stochasticity allows the agent to achieve from any set the maximal element according to her underlying preferences over lotteries.

Stochastic Diagonalization [PDF]
Physics Reports, 1999 Conventional Quantum Monte Carlo methods, routinely used to compute properties of many-body quantum systems, often suffer from what has been termed 'minus-sip'' problems. These problems are shown to result from an elementary property of the Hamiltonian and the use of stochastic (Markovian) simulation methods to compute physical quantities.

Local linear modelling of the conditional distribution function for functional ergodic data
Mathematical Modelling and Analysis, 2022 The focus of functional data analysis has been mostly on independent functional observations. It is therefore hoped that the present contribution will provide an informative account of a useful approach that merges the ideas of the ergodic theory and ...

Stochastic superoptimization [PDF]
ACM SIGARCH Computer Architecture News, 2013 We formulate the loop-free binary superoptimization task as a stochastic search problem. The competing constraints of transformation correctness and performance improvement are encoded as terms in a cost function, and a Markov Chain Monte Carlo sampler is used to rapidly explore the space of all possible programs to find one that is an optimization of ...

Optimal Maintenance Policy for a Technical System Subject to Hidden Faults and Randomly Occurring Hazards [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2021 The paper presents a method of finding the optimal time between inspections for a system subject to degradation-related faults which make the system vulnerable to randomly occurring external hazards that may cause its damage.

Stochastic Multiresonance [PDF]
Physical Review Letters, 1997 We present a class of systems for which the signal-to-noise ratio as a function of the noise level may display a multiplicity of maxima. This phenomenon, referred to as stochastic multiresonance, indicates the possibility that periodic signals may be enhanced at multiple values of the noise level, instead of at a single value which has occurred in ...

Local linear approach: Conditional density estimate for functional and censored data
Demonstratio Mathematica, 2022 Let YY be a random real response, which is subject to right censoring by another random variable CC. In this paper, we study the nonparametric local linear estimation of the conditional density of a scalar response variable and when the covariable takes ...
