Risk aware minimum principle for optimal control of stochastic differential equations [PDF]

open access: yesarXiv, 2018
We present a probabilistic formulation of risk aware optimal control problems for stochastic differential equations. Risk awareness is in our framework captured by objective functions in which the risk neutral expectation is replaced by a risk function, a nonlinear functional of random variables that account for the controller's risk preferences.

The non-linear trade-off between return and risk: a regime-switching multi-factor framework [PDF]

open access: yesarXiv, 2014
This study develops a multi-factor framework where not only market risk is considered but also potential changes in the investment opportunity set. Although previous studies find no clear evidence about a positive and significant relation between return and risk, favourable evidence can be obtained if a non-linear relation is pursued.

Developing a cardiovascular disease risk factor annotated corpus of Chinese electronic medical records [PDF]

open access: yesarXiv, 2016
Cardiovascular disease (CVD) has become the leading cause of death in China, and most of the cases can be prevented by controlling risk factors. The goal of this study was to build a corpus of CVD risk factor annotations based on Chinese electronic medical records (CEMRs).

Risks of Large Portfolios [PDF]

open access: yesarXiv, 2013
Estimating and assessing the risk of a large portfolio is an important topic in financial econometrics and risk management. The risk is often estimated by a substitution of a good estimator of the volatility matrix. However, the accuracy of such a risk estimator for large portfolios is largely unknown, and a simple inequality in the previous literature
