Combined Stochastic Process and Value at Risk: A Real-World Information System Decision Case [PDF]

Entropy, 2019
In this study, we used a combined stochastic process and value-at-risk (VaR) method to examine an electronic commerce expansion decision. By modeling uncertain benefits as a stochastic process, maximum losses of alternative decisions were quantified and ...

Convergence of stochastic process with Markov switching [PDF]

Математичні Студії, 2012
It has been established sufficient conditions for the convergence of a multi-dimensional stochastic process in the case of dependence of the regression function on the environment, which is described by Markov switchings.

Asymptotic Normality of Nonparametric Kernel Regression Estimation for Missing at Random Functional Spatial Data

Journal of Mathematics, 2023
This study investigates the estimation of the regression function using the kernel method in the presence of missing at random responses, assuming spatial dependence, and complete observation of the functional regressor.

Meta-Learning Amidst Heterogeneity and Ambiguity

IEEE Access, 2023
Meta-learning aims to learn a model that can handle multiple tasks generated from an unknown but shared distribution. However, typical meta-learning algorithms have assumed the tasks to be similar such that a single meta-learner is sufficient to ...

Commentary to “Delay time in the transfer of modulation between microwave beams”

Engineering Reports, 2022
New results, as reported in a forthcoming paper (Cacciari & Ranfagni, 2022), induced us to modify our point of view on the origin of the transfer of modulation between microwave beams. We believe that a commentary and addition of information to the paper
