The impact of model risk on dynamic portfolio selection under multi-period mean-standard-deviation criterion [PDF]

open access: yesEuropean Journal of Operational Research, 2018
We quantify model risk of a financial portfolio whereby a multi-period mean-standard-deviation criterion is used as a selection criterion. In this work, model risk is defined as the loss due to uncertainty of the underlying distribution of the returns of

Advancing nearshore and onshore tsunami hazard approximation with machine learning surrogates [PDF]

open access: yesNatural Hazards and Earth System Sciences
Probabilistic tsunami hazard assessment and probabilistic tsunami risk assessment (PTHA and PTRA) are vital methodologies for computing tsunami risk and prompt measures to mitigate impacts. However, their application across extensive coastlines, spanning

Model Risk Measurement under Wasserstein Distance [PDF]

open access: yes, 2018
The paper proposes a new approach to model risk measurement based on the Wasserstein distance between two probability measures. It formulates the theoretical motivation resulting from the interpretation of fictitious adversary of robust risk management ...

Model risk of expected shortfall

open access: yesJournal of Banking & Finance, 2019
In this paper we study the model risk of Expected Shortfall (ES), extending the results of Boucher et al. (2014) on model risk of Value-at-Risk (VaR). We propose a correction formula for ES based on passing three backtests.

Local Linear Approximation Algorithm for Neural Network

open access: yesMathematics, 2022
This paper aims to develop a new training strategy to improve efficiency in estimation of weights and biases in a feedforward neural network (FNN). We propose a local linear approximation (LLA) algorithm, which approximates ReLU with a linear function at

Risk prediction models [PDF]

open access: yesNephrology Dialysis Transplantation, 2013
Prognostic research focuses on the prediction of the future course of a given disease in probability terms. Prognostication is performed by clinical decision makers by using risk prediction models that allow us to estimate the probability that a specific event occurs in a given patient over a predefined time period conditional on prognostic factors ...
