Online Optimization for Network Resource Allocation and Comparison with Reinforcement Learning Techniques

no code implementations16 Nov 2023 Ahmed Sid-Ali, Ioannis Lambadaris, Yiqiang Q. Zhao, Gennady Shaikhet, Amirhossein Asgharnia

The system operates in discrete time; at each time slot, the administrator reserves resources at servers for future job requests, and a cost is incurred for the reservations made.

Online Optimization for Randomized Network Resource Allocation with Long-Term Constraints

no code implementations24 May 2023 Ahmed Sid-Ali, Ioannis Lambadaris, Yiqiang Q. Zhao, Gennady Shaikhet, Shima Kheradmand

If certain job requests cannot be satisfied, there is a violation that engenders a cost to pay for each of the blocked jobs.

Estimating value at risk and conditional tail expectation for extreme and aggregate risks

no code implementations29 Jan 2021 Suman Thapa, Yiqiang Q. Zhao

In this paper, we investigate risk measures such as value at risk (VaR) and the conditional tail expectation (CTE) of the extreme (maximum and minimum) and the aggregate (total) of two dependent risks.

Construction of New Copulas with Queueing Application

no code implementations29 Jan 2021 Suman Thapa, Yiqiang Q. Zhao

In this paper, we construct a bound copula, which can reach both Frechet's lower and upper bounds for perfect positive and negative dependence cases.
