Fuzzy portfolio optimization problem under uncertainty conditions with application of computational intelligence methods

open access: yesSistemnì Doslìdženâ ta Informacìjnì Tehnologìï, 2020
The problem of constructing an optimal securities portfolio under uncertainty is considered along with the direct and dual problems of fuzzy portfolio optimization. The modified fuzzy portfolio optimization problem is also suggested under a constraint on

Portfolio optimization based on neural networks sensitivities from assets dynamics respect common drivers

open access: yesMachine Learning with Applications, 2023
We present a framework for modeling asset and portfolio dynamics, incorporating this information into portfolio optimization. We define drivers for asset and portfolio dynamics and their optimal selection. For this framework, we introduce the Commonality

Robustness-based portfolio optimization under epistemic uncertainty

open access: yesJournal of Industrial Engineering International, 2018
In this paper, we propose formulations and algorithms for robust portfolio optimization under both aleatory uncertainty (i.e., natural variability) and epistemic uncertainty (i.e., imprecise probabilistic information) arising from interval data ...
