Asymptotic optimality in stochastic optimization [PDF]

open access: yesThe Annals of Statistics, 2021
We study local complexity measures for stochastic convex optimization problems, providing a local minimax theory analogous to that of Hájek and Le Cam for classical statistical problems. We give complementary optimality results, developing fully online methods that adaptively achieve optimal convergence guarantees. Our results provide function-specific

Stochastic Optimization Forests

open access: yesManagement Science, 2023
We study contextual stochastic optimization problems, where we leverage rich auxiliary observations (e.g., product characteristics) to improve decision making with uncertain variables (e.g., demand). We show how to train forest decision policies for this problem by growing trees that choose splits to directly optimize the downstream decision quality ...

Stochastic polynomial optimization [PDF]

open access: yesOptimization Methods and Software, 2019
This paper studies stochastic optimization problems with polynomials. We propose an optimization model with sample averages and perturbations. The Lasserre type Moment-SOS relaxations are used to solve the sample average optimization. Properties of the optimization and its relaxations are studied. Numerical experiments are presented.

Information Loss Due to the Data Reduction of Sample Data from Discrete Distributions

open access: yesData, 2020
In this paper, we study the information lost when a real-valued statistic is used to reduce or summarize sample data from a discrete random variable with a one-dimensional parameter. We compare the probability that a random sample gives a particular data

Numerical simulations for stochastic meme epidemic model

open access: yesAdvances in Difference Equations, 2020
The primary purpose of this study is to perform the comparison of deterministic and stochastic modeling. The effect of threshold number is also observed in this model.

Probabilistic Optimization Techniques in Smart Power System

open access: yesEnergies, 2022
Uncertainties are the most significant challenges in the smart power system, necessitating the use of precise techniques to deal with them properly. Such problems could be effectively solved using a probabilistic optimization strategy.

A New Stochastic Process of Prestack Inversion for Rock Property Estimation

open access: yesApplied Sciences, 2022
In order to enrich the current prestack stochastic inversion theory, we propose a prestack stochastic inversion method based on adaptive particle swarm optimization combined with Markov chain Monte Carlo (MCMC).

Effects of Probability Function on the Performance of Stochastic Programming [PDF]

open access: yesJournal of Optimization in Industrial Engineering, 2018
Stochastic programming is a valuable optimization tool where used when some or all of the design parameters of an optimization problem are defined by stochastic variables rather than by deterministic quantities.
