Re‑Imagining Risk: The Role of Resilience and Prevention

"I argue that that conventional risk analysis—meaning risk analysis fixated on controlling risks—should expand to systematically integrate two related principles. The first is prevention, which seeks in the first instance to avoid the risk altogether. The second is resilience, which aims build the capacity to respond to whatever does come to pass."

Stochastic measure distortions induced by quantile processes for risk quantification and valuation

Date : Tags : , , , ,
" The introduced valuation principle relies on stochastic ordering so that the valuation risk-loading, and thus risk premiums, generated by the measure distortion is an ordered parametric family. The quantile processes are generated by a composite map consisting of a distribution and a quantile function."

Reinforcement Learning with Dynamic Convex Risk Measures

"We develop an approach for solving time-consistent risk-sensitive stochastic optimization problems using model-free reinforcement learning (RL). Specifically, we assume agents assess the risk of a sequence of random variables using dynamic convex risk measures. We employ a time-consistent dynamic programming principle to determine the value of a particular policy, and develop policy gradient update rules. We further develop an actor-critic style algorithm using neural networks to optimize over policies. Finally, we demonstrate the performance and flexibility of our approach by applying it to optimization problems in statistical arbitrage trading and obstacle avoidance robot control."

How AI regulation is developing in the insurance industry

"... insurance carriers should internally organize key stakeholders related to AI strategy and development to collaboratively evaluate how they define and develop AI projects and models. If carriers have not yet established broad life cycle governance or risk management practices unique to their AI/machine learning systems, they should begin that journey with haste."
