Linear statistical inference for global and local minimum variance portfolios [PDF]

open access: yes
Traditional portfolio optimization has been often criticized since it does not account for estimation risk. Theoretical considerations indicate that estimation risk is mainly driven by the parameter uncertainty regarding the expected asset returns rather

Belief Propagation Algorithm for Portfolio Optimization Problems

open access: yes, 2010
The typical behavior of optimal solutions to portfolio optimization problems with absolute deviation and expected shortfall models using replica analysis was pioneeringly estimated by S. Ciliberti and M. M\'ezard [Eur. Phys. B.

Toward Capacitive In‐Memory‐Computing: A Device to Systems Level Perspective on the Future of Artificial Intelligence Hardware

open access: yesAdvanced Intelligent Discovery, EarlyView.
Capacitive, charge‐domain compute‐in‐memory (CIM) stores weights as capacitance,eliminating DC sneak paths and IR‐drop, yielding near‐zero standbypower. In this perspective, we present a device to systems level performance analysis of most promising architectures and predict apathway for upscaling capacitive CIM for sustainable edge computing ...

Portfolio Decisions with Higher Order Moments [PDF]

open access: yes
In this paper, we address the global optimization of two interesting nonconvex problems in finance. We relax the normality assumption underlying the classical Markowitz mean-variance portfolio optimization model and consider the incorporation of skewness

Portfolio optimization with mixture vector autoregressive models

open access: yes, 2020
Obtaining reliable estimates of conditional covariance matrices is an important task of heteroskedastic multivariate time series. In portfolio optimization and financial risk management, it is crucial to provide measures of uncertainty and risk as ...

Noisy Covariance Matrices and Portfolio Optimization

open access: yes, 2001
According to recent findings [1,2], empirical covariance matrices deduced from financial return series contain such a high amount of noise that, apart from a few large eigenvalues and the corresponding eigenvectors, their structure can essentially be ...

Radiation emergency medical countermeasures: Current formulary, identified gaps, and future approaches

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Current radiation medical countermeasures primarily focus on hematopoietic acute radiation syndrome (H‐ARS) using agents like granulocyte colony‐stimulating factor (G‐CSF), granulocyte‐macrophage colony‐stimulating factor (GM‐CSF), and romiplostim, alongside treatments for internal contamination (Prussian blue, diethylenetriamine pentaacetate [DTPA ...

A Polynomial Optimization Approach to Constant Rebalanced Portfolio Selection [PDF]

open access: yes
We address the multi-period portfolio optimization problem with the constant rebalancing strategy. This problem is formulated as a polynomial optimization problem (POP) by using a mean-variance criterion.

Portfolio optimization using particle swarm optimization method [PDF]

open access: yesتحقیقات مالی, 2010
The Markowitz’s optimization problem is considered as a standard quadratic programming problem that has exact mathematical solutions. Considering real world limits and conditions, the portfolio optimization problem is a mixed quadratic and integer ...

Differential Evolution for Multiobjective Portfolio Optimization [PDF]

open access: yes
Financial portfolio optimization is a challenging problem. First, the problem is multiobjective (i.e.: minimize risk and maximize profit) and the objective functions are often multimodal and non smooth (e.g.: value at risk).
