Bayesian fuzzy optimization using fuzzy Gaussian process
Sourav Das, Debdas Ghosh, Debjani Chakraborty +1
In many real-life problems, decision-making gets complicated due to dual sources of uncertainty, known as randomness and fuzziness or imprecision, which can be challenging for trad…
Fritz-John optimality condition in fuzzy optimization problems and its application to classification of fuzzy data
Fangfang Shi, Guoju Ye, Wei Liu +1
The main objective of this paper is to derive the optimality conditions for one type of fuzzy optimization problems. At the beginning, we define a cone of descent direction for fuz…
Generalized Hukuhara Hadamard Derivative of Interval-valued Functions and Its Applications to Interval Optimization
Ram Surat Chauhan, Debdas Ghosh, Qamrul Hasan Ansari
In this article, we study the notion of gH-Hadamard derivative for interval-valued functions (IVFs) and its applications to interval optimization problems (IOPs). It is shown that…
Generalized Hukuhara Weak Subdifferential and its Application on Identifying Optimality Conditions for Nonsmooth Interval-valued Functions
Suprova Ghosh, Debdas Ghosh
In this article, we introduce the idea of -weak subdifferential for interval-valued functions (IVFs) and show how to calculate -weak subgradients. It is observed that a non…
Generalized-Hukuhara Subgradient Method for Optimization Problem with Interval-valued Functions and its Application in Lasso Problem
Debdas Ghosh, Amit Kumar Debnath, Radko Mesiar +1
In this study, a \emph{-subgradient technique} is developed to obtain efficient solutions to the optimization problems with nonsmooth nonlinear convex interval-valued functions…
Generalized-Hukuhara Subdifferential Analysis and Its Application in Nonconvex Composite Optimization Problems with Interval-valued Functions
Anshika, Debdas Ghosh, Ram Surat Chauhan +1
In this article, we study -subdifferential calculus of convex interval-valued functions (IVFs) and apply it in a nonconvex composite model of interval optimization problems (IO…
