Zadovoljstvo nam je pozvati vas na 55. Fakultetski seminar koji će se održati u srijedu, 18.05.2022., s početkom u 12h, u amfiteatru A1-1.
Seminar će održati dr. sc. Ilgim Yaman, Giresun Univesity (Turska) na temu:
Portfolio optimization based on nonlinear neural network
Portfolio selection problem is a very popular optimization problem in the optimization world. Harry Markowitz  had proposed standard portfolio optimization in 1952. In the Portfolio optimization problem main goal is minimizing the risk, while maximizing the expected return of portfolio. Because of portfolio optimization problem is an NP-hard problem, many heuristic methods were used to solve portfolio optimization method such as particle swarm optimization, ant colony optimization etc. Since portfolio optimization problem is a quadratic programming (QP) problem, in 2019, we integrate the neural network which represented in 2014 by Yan , in to standard portfolio optimization problem . Proposed neural network is based on solving primal and dual problems simultaneously . In 2021, we proposed another method to solve cardinality constrained portfolio optimization problem . In this study, we combine genetic algorithm and nonlinear neural network to limited the number of assets in the portfolio. In this Erasmus mobility course, portfolio optimization and the proposed methods will be present.
